Introduction

DISCRIBE CD Mastering Software
Thank You for purchasing CharisMac Discribe, the Ul­timate CD Recording software! Discribe was designed to allow you to easily take advantage of all the features of your CD recorder. You can do some amazing things with Discribe. Like to make music? You can record a music CD from any combination of MP3/AIFF/SDII/ WAV files, or even live audio from the included Audi­oScribe application. Discribe supports the full range of CD-R/RW dri ves that hav e been in the market ov er the past few years, including ATAPI/EIDE, SCSI, USB, and Firewire (IEEE1394) interface drives.
Novice and experienced users alike will find Discribe easy and intuitive to use. For users new to CD record­ing, the Discribe Quick Start provides a unique “Anti­Wizard” interface that can create a CD in as few as 2 mouse clicks. The Quick Start performs the common CD recording tasks: CD-to-CD copies, Audio CD cre­ation from any combination of MP3/AIFF/SDII/WAV files or CD tracks, and Data CD-ROM creation.
By clicking the “close window” button on the Quick Start screen, you enter the Discribe Main Application. Here you will find an advanced CD creation environ­ment that will give you flexibility in creating your CD projects. For example, when you create an audio CD in the full application, you can rearrange or rename tracks, change the name of your CD, record in Disc­At-Once mode, and more. In the full application you can also create advanced format CDs such as Mac/ ISO9660 Hybrid discs. Be sure to visit the Charismac website often for updates to the Discribe software. www.Charismac.com

Getting Started

System Requirements

Before installing Discribe, check that you have these minimum system requirements:
Internet access is recommended to take advantage of all Discribe’s features.

Installing Discribe

Before installing Discribe please take the following precautions:
Getting Started
• Power PC or greater Macintosh
• 32Mb RAM
• Quicktime 2.0 or better (Quicktime 4.0 or higher recommended)
• Supported CD recorder (for the most current list, please visit www.charismac.com)
• Mac OS 8.0 (Mac OS 8.6 or newer recommended, depending on CD recorder)
• Remove any non-Apple and third party CD-ROM Drivers. We recommend you remove any CD­ROM driv er e xtensions from other manuf acturers. The included CD-ROM Extension is capable of supporting virtually all SCSI, AT API and USB CD­ROM and CD-R/R W drives on the mark et allowing you to use one CD driver for all of your CD-R OM and CD-R/RW devices, including the original CD­ROM drive provided by Apple.
• If installing software for USB or Firewire based CD recorders, you may want to remove any third party USB or Firewire drivers, or e xtensions. These drivers may lead to conflicts, which can cause your
5
DISCRIBE CD Mastering Software
recorder to not be seen by the Discribe software.
Discribe must be installed on a hard disk. Once you have installed the software, store the original program CD-ROM in a safe place.
1. Disable any unnecessary extensions and restart your Macintosh prior to installing Discribe. In some cases, extensions may interfere with the soft­ware installation process, causing the Macintosh to generate errors and forcing a restart.
2. Insert the Discribe Installation CD-ROM in your system’s CD-ROM drive.
3. If the Discribe CD-ROM window does not open automatically, double click the CD-ROM icon to open the window.
4. Double-click on the Discribe Installer file icon. Follow the on-screen instructions, read and agree to the end user license agreement.

Overview

Overview

A Word About CD-R and CD-RW

CD-R
is the term used to denote CD-Recordable me­dia, or discs. CD-R discs are recorded permanently. Once information is written, it cannot be erased. Data can be added until the disc is full (see “Multi-Session recording). CD-R media is good for creating archived information that does not need to be changed, or for distribution thanks to the rapidly declining price of CD-R media over the past few years.
CD-RW
dia. CD-RW media allo ws your CD-R W dri ve to erase the disc, and then write to the media again as your backup scheme requires. CD-RW media is rated for approximately one thousand complete writes to the media (the actual number of writes may vary depend­ing upon type and brand of media). CD-R and CD-RW drives differ only in the fact that CD-RW drives can write to both CD-R and CD-RW discs.
CD-RW drives are also capable of erasing CD-RW discs (through the Discribe interface) and allowing you to write to them again. Discribe handles the writ­ing process to either CD-R or CD-RW media in the e x­act same fashion. The steps of writing to a CD are exactly the same with the exception of which type of media is inserted prior to the write process (CD-R or CD-RW). With this in mind, the term CD-RW will be used throughout this manual to denote a CD-Record­able device, disc or format.

ed by the Discribe splash screen. After a few seconds
the splash screen will give way to Discribe’s Quick Start menu.

Discribe’s Quick Start Menu

While unlike a traditional “wizard” this menu allows for quick and easy selection of the most commonly used functions:
burning Data CDs (HFS), Audio CDs and Disc Copy.
10
Quick Start
Y ou’ ll also find buttons that provide you with addition­al information about your recorder and disc informa­tion for the disc in the recorder. Additionally, you can extract audio tracks from CDs or launch AudioScribe; the direct-to-disk recording application included with Discribe.
To get started, you can make your selection from one of the three main choices presented, drag files you wish to write to CD to auto-select the disc format, or you can click the Close Window box to reveal Dis­cribe’s other more powerful functions in Discribe’s main window.

Discribe’s Other Functions

If the disc format you wish to write to CD is not a part of the Quick Start menu, don’t fret. Discribe has a host of other powerful features that can be accessed through the main interface. Upon launch of Discribe just click the close window box in the upper left corner of the interface. This will reveal the main interface. You can select any format from the pop-up menu to create just about any type of CD-ROM.
By default, the main interface will default to the Mac-

intosh HFS option.

Macintosh HFS

The Macintosh HFS function copies data from a mounted volume to a CD. The volume can be a hard disk, hard disk partition, CD-ROM, remov able media, mounted disk image, etc. of any size, but must contain less than 650 MB of data. This option allows you to set up a disc exactly the way that you want it to look (icon placement, arrangement of windows, window views, whether or not the CD-ROM’ s window should be open by default, etc.) and write it to a CD for an exact dupli­cate.
30
Main Functions
NOTE
Note: It is not recommended that you write CDs from mounted server volumes. Server traffic can be unpr edictable in natur e and can cause a write failure due to lack of throughput.

Setting Up Your Volume

Set your volume up any way you like it. K eep in mind that the name of the volume will become the name of the CD, and the volume’s icon will become the CD’s icon. Name and paste the icon you want the CD to have onto the volume, you can do this by doing a Get Info on the volume’s mounted disk icon.
Once you have your volume set up simply drag the icon of the volume from the desktop of your Macin­tosh to the Discribe window.
An options dialog box will appear for the volume
31
DISCRIBE CD Mastering Software
you’ve dragged over.
Create a Mac / ISO Hybrid - Checking this op­tion allows you to create a Hybrid CD-ROM (cov­ered later in this manual).
Bootable - If checked, Discribe will prompt for a bootable CD to be inserted into the CD writer so that driver information can be read from a known good bootable CD. For best results, use your most current Apple system CD available. Remember that this volume has to meet certain requirements:
• Cannot be your Macintosh’s startup volume
• All files must be closed and must appear just as you want them on the CD
• Total volume size must be small enough to fit on the CD
• Ensure you have emptied the trash
• Don’t write from a volume used by Discribe
For more information on the creation of bootable CDs see the section of Creating a Bootable CD-ROM later in this manual.
Select the desired options and click OK. Discribe’s in­terface will update to show the new volume has been added.
32
Main Functions

Adding Audio

Discribe will allow you to add audio to the end of your data track, if you wish to add audio you can simply drag-n-drop an audio file on the window. Or you can click the A udio... b utton for the Audio Pick er window. If you’ve added audio tracks into the Audio Picker window, click OK to proceed to the write process.

Writing the CD

Once the data has been added and arranged to your sat­isfaction just click OK to return to the Discribe main window. Verify that the correct CD-RW writer is se­lected then click the Write Disc... button. Set up your options for T est Write, In Background, Open Ne xt Ses­sion, Write Speed and Verify After Writing, then click the Start button to begin the write process.

Multi-Session Macintosh HFS CD-ROMs

There is nothing special that needs to be done to write multiple Macintosh HFS sessions to a CD other than selecting the Open Next Session option in the Write Options Screen.
NOTE
Note: Macintosh HFS multi-session CD-ROMs can really be called multi-volume. When a multi-session Macintosh HFS CD­ROM is mounted an icon for each Macintosh HFS session written to the CD will mount on the desk-top. To eject the CD you will need to drag all the CD’s icons to the trash.

A Word About Multi-Session ISO-9660 XA CD­ROM Discs
One of the great things about the ISO-9660 XA format is it’s ability to write single v olume multi-session CD­ROM. Using the abov e instructions, write a session us­ing the ISO-9660 XA format. When you wish to write the second session to the CD you set your data up the same way you always do using the instructions above.
While in the ISO-9660 Picker window, be sure click the Import Session button, when Discribe prompts you to, insert the previously written CD into the re­corder. Discribe will read the existing data into the ISO-9660 Picker, click OK and proceed with the write as usual. You can write another session or finalize the disc at your discretion.
NOTE
Note: If you write an ISO 9660-XA session to a disc that already has an ISO-9660 XA session without using the Import Session button the first session of the CD will be lost and unrecoverable. Only the new data written to the CD will be recognized.

Mac/ISO Hybrid

Discribe has the ability to write a Macintosh HFS CD­ROM along with ISO-9660 data on the same CD­ROM. The beauty of this type of CD is that it contains a self contained Mac HFS volume, and a self-con­tained ISO-9660 volume and both volumes have the ability to share data between each other.
For example, you can create a CD-R OM that contains Mac specific web pages on the Mac portion of the CD­ROM, and PC specific web pages on the ISO side of the CD-ROM, neither platform can see each others da­ta. With that in mind, you can share common image files between both platforms so that all the images that are common for both sites are only written to the CD once, yet both platforms can still display the images.

Setup of Data

In setup of a Hybrid CD-ROM, it is required that the Mac only data, and data that is intended to be shared across to the ISO side of the CD, reside on it’s o wn vol­ume. The PC only data can reside anywhere on your hard disk other than the volume set aside for Mac and shared data.

DVD Video/A udio

Discribe’s DVD (Digital Versatile Disc) Video/Audio function allows you to write DVD video and audio as well as data to CD-R, CD-RW, DVD-R, DVD-RW, DVD+R and DVD+RW media. Please note that in or­der to write to DVD-R, DVD-RW, DVD+R and DVD+RW you will need a DVD drive capable of han­dling each type of media.
The data is written in the UDF Format (Universal Disc Format) and is cross-platform compatible working on any platform that supports reading UDF discs.
In theory, any disc written in this format with video data will be readable in a DVD set-top reader for play­back. Limitations will include the set-top reader’s ability to work with the individual disc itself. The set­top reader’s ability to handle different media types (CD-R, CD-RW, DVD-R, DVD-RW, DVD+R and DVD+RW) is dependant upon several factors.

Troubleshooting

The following list includes some common problems that might be encountered while working to create your CD.
Q: Does Discribe work with iTunes? A: Discribe 4.5 includes a Firewire driver that allows
iTunes to write to a supported CD-RW drive. Be sure to disable the Firewire Authoring Support and Author­ing Support files which get installed with the iTunes installer.
Q: Why do audio CDs work in my computer but not in my audio CD player or DVD player?
A: The most common reason that an audio CD player or a DVD player will have an issue with a particular disc is due to the media’s reflecti vity . Some players are very sensitive to the reflectivity of the disc itself and have trouble reading CD-RW media. CD-RW media, in general, will be far less compatible than CD-R me­dia will. Try using dif ferent brands of CD-R media un­til you find one that works well with your player.
Glossary
Q: I get a message before I attempt to write a CD that
says “A valid CD-R drive must be selected...” A: If you encounter a message that says, “a valid CD-
R drive must be selected...” then your Mac and Dis­cribe are not detecting your CD-RW dri ve and they are unable to communicate with it. There are a series of simple steps that you can go through to troubleshoot this problem:
1. Check to see if the correct extensions are loading. Many USB and Firewire drives require special exten­sions that must load in order for Discribe to identify the drive.
If you have the correct extensions loading and still can-
69
DISCRIBE CD Mastering Software
not see the drive, here are a few more suggestions:
1. Quit Discribe and then cycle the power on your CD­RW drive (turn it off for 20 seconds and then turn it back on). Now reopen Discribe and see if the drive is detected.
2. Turn off your Mac. Now turn off the CD-RW dri ve. With everything off, unplug both ends of the USB ca­ble, from the Mac and from the Spressa drive. Plug both cables back in and then turn the CD-RW drive back on.
Now boot the computer back up and reopen Discribe and see if the CD-RW drive appears by clicking the Recorder Information.
3. Try turning your CD-RW drive off, then Unplug the CD-RW drive from the power outlet. Reboot your Mac. After the Mac has completed its boot c ycle, then turn the CD-RW drive back on. After the CD-RW drive’s yellow access light goes out, launch Discribe. Click Discribe’s Recorder Information button, the CD-RW drive should show up.
4. Try connecting the CD-RW drive directly to you Mac rather than through a hub or your keyboard. If you are going directly into your Mac try switching the ports between the keyboard and the CD-RW drive.
Write Test Failure
The write test simulates writing data to the CD by ex­actly duplicating the write process while holding the recorder’s write laser in the off state. If this test is failed, check the following:
Fragmentation
If the files to be recorded are fragmented (not written cleanly and contiguously) on the hard drive, the time
70
Glossary
consumed in accessing them may cause the recorder’s buffers to “run out” of information temporarily. Dur­ing the actual write process, this would make the disc being written to useless. Use Norton TM Speed Disk or another drive utility to test the hard drive for frag­mentation. If fragmentation is greater than moderate, you will need to reinitialize to optimize the hard drive.
Hard Drive Too Slow
If you have an older hard drive, it may be too slow in transferring data to the recorder. T ry using a slo wer re­corder speed (1X or 2X). If you are still not successful, you need a faster hard drive.
Recorder Won’t Play CD-ROM
Most recorders can be used to play back CD-ROMs, some older recorders cannot.
Check your manufacturer’s documentation and make sure the CD-ROM Extension is loaded. Ensure also that the device is connected and turned on before you start up your Macintosh, otherwise the CD-ROM Ex­tension will be unable to see the device to load a device driver .
CD Recorder Not Accessible
SCSI - Like other SCSI devices, CD recorders must have a correctly set SCSI ID, a properly terminated SCSI connection, currently supported by Discribe and must be started before the Macintosh in order to show up on the SCSI bus. Refer to the recorder manufacturer and Apple documentation for information. Refer to the user manual
List of Supported CD Recorders or the Discribe read me for the latest up to date information regarding sup­port for your recorder.

Note that SCSI IDs 0, 3 (internal CD player), and 7 are generally re-served for the Macintosh itself.
ATAPI - It is possible that the driv e was unable to re g­ister it’s ‘bios’ information with the Macintosh at boot time. This would hinder any software’s ability to see the drive connected to the Mac. Check your CD-RW drives IDE and power cabling to ensure a firm fit.
USB / Firewire - Make sure that the proper software is loading in the System Folder. Items to double check are the USB (USB manager V1.2 or higher) or Firewire (Firewire V2.1 or higher) drivers (available from Apple) and the USB or Fire wire SIM that w ould have come with the hardware, all of which should be loaded in the Extensions folder. Also check to ensure a tight fit for all USB or Firewire cabling. Faster Record­er Speeds not Available Only those speeds (1X, 2X, etc.) which your recorder is capable of will appear in the Discribe Screen.
Note that CD-RW write speeds are often slower than standard CD-RW write speeds. Many CD-RW drives are distinguished in the following way: 8x4x24. In this ex-ample, the recorder would record to CD-R W media at speeds up to 8x, CD-RW media at speeds up to 4x and read CDs at speeds up to 24x.

Glossary of CD and DVD Terms

AC-3 Dolby® digital surround sound for DVD-Video capable of playing 5.1 discrete channels of audio for the ultimate in surround sound (example, front set of left & right speakers, center channel, rear set of left & right surround speakers + subwoofer). Playing back AC-3 encoded audio requires a Dolby® AC-3 compat­ible receiver & the appropriate speakers to be connect­ed to the DVD-Video player or DVD-ROM drive. DVD-Video players & DVD-ROM drives can also play the audio as regular stereo for non AC-3 systems
A-Time An abbreviated form of Absolute Time. In CD-DA, the time elapsed since the beginning of the disc. Can be used in determining the start and stop times of sound segments for programming an applica­tion on a Mixed Mode disc, measuring from the very beginning of the data area (including the computer data in Track 1).
Absolute Time In Pre-Gr oove (ATIP) Absolute time on the disc from the very first addressable block in the PCA (Power Calibration Area) on a CD-R or CD-RW disc Access To find a piece of information on a memo­ry medium.
Glossary
Access Time The time it takes to retrie ve a piece of in-
formation. W ith disks or discs, maximum access time is measured as the time it takes to move from one end of the disc to the other, find a piece of information, and transfer that information to RAM.
Archive A term referring to the long term storage data. Normally, archiving involves removing a file from on­line storage because it doesn’t need to occupy valuable hard drive space, yet it is too valuable to be deleted or will be used again later. Long-life optical media such as CD-R, CD-RW, MO, or DVD+R W are highly desir ­able for archiving.

ASMO (Previously called MO7) a high capacity Mag­neto-Optical drive capable of storing up to 7Gb of computer data, on a removable rewritable optical car­tridge. ASMO drives may also be able to read CD­ROM & potentially DVD-ROM discs
A TAPI A T Attachment Peripheral Interface. Also known as Enhanced IDE (EIDE), this interface is used to attach storage devices such as hard disk drives, CD­ROM drives, CD recorders, and DVD-ROM drives to PC systems. ATAPI is capable of addressing up to 4 drives, and capable of transfer rates up to 16.5Mb per second.
ATIP See Absolute Time In Pre-Groove Authoring Software A set of software that allows
non-programmers to design and create programs (e.g., multi-media presentations) by entering commands or menu choices, without having to know a programming language.
Backup Backups are usually data that has been copied from one medium to another, so an additional copy of the data will exist should something happen to the original version. Nowadays, as strategically important corporate data becomes scattered across literally thou­sands of PC’s, good backup strategies- and high-ca­pacity storage -are essential to a company’ s continuous function.
Binary This is how computers store digital informa­tion-in a series of ones and zeroes, or “ons” and “offs”.
Bit The smallest piece of data in a computer, it repre­sents a single one or zero.
Block The user data portion of a logical sector in CD­ROM formats Block Error Correction The addition of 272 bytes of error correction code (ECC) at the of each block of data during pre-mastering, to allow correction

of errors detected in the user data block. Bridge Disc A technique for storing data on a CD-
ROM/XA disc that allows it to be played back on a CD-I and Photo-CD player, and a CD-ROM drive.
Buffer A piece of memory that temporarily stores da­ta, usually a small amount. This can help to compen­sate for differences in the rate of data from one device to another, or can be used to store small pieces of in­formation that are likely to be used repeatedly (such as a digitized beep or other sound). Most CD-ROM drives have their own 64-kilobyte buffers, so that if you ask for, say 24 Kilobytes of data, they will be there for instant retrieval. Otherwise they are simply wiped out of the buffer when the next set of data is loaded. CD recorders use data buffers to ensure a steady stream of data from the host computer to the CD re­corder. If a CD recorder’s buffer becomes empty dur­ing recording, a “buffer underrun” error occurs. this can mean that the disc is no longer usable (for CD-R discs). W ith CD-ReWritable (CD-RW), the disc can be re-recorded.
Byte A sequence of bits (usually eight on the computer or fourteen on a compact disc) representing an alpha­numeric symbol. Used to measure the capacity of memory media.
Cache A performance booster for drives, caching works by storing information read from the drive in high-speed random access memory. When the comput­er requests information from the drive, the drive checks it relatively speedy cache for the information before looking on the disks itself. If the information is on the cache, it sent to the computer without a relative­ly slow disk access.

CD-DA Compact Disc-Digital Audio. Jointly devel­oped by Philips and Sony and launched in 1983, CD­DA is the first and most popular incarnation of the compact disc, used to digitally record and play back music at unprecedented quality. It has gained world­wide acceptance as a standard to which all digital au­dio CD discs and CD drives adhere. Philips/Sony’s CD-DA standard is known as the Red book.
CD-Erasable (CD-E) Predecessor to CD-ReWritable. The products are exactly the same, but the name was officially changed in 1994 to CD-ReWritable.
CD-Extra See Enhanced CD CD-I Compact Disc-Interactive, Philips’ entry into
the consumer Compact Disc market. It is a compact disc format designed to allow interactive multimedia application to be played through a small computer/disc player on a home television screen. Especially good real-time animation, video, and sound. The CD-I stan­dard is also known as the Green Book.
CD-I Ready A set of specifications which define a way of recording
CD-I information on a CD-DA disc. CD-Plus See Enhanced CD CD-MO Compact Disc-Magneto Optical systems are
used as high-density storage media. They have an ac­cess speed slower than a magnetic hard disk but faster than CD-ROM. The discs are written by a po werful la­ser heating a spot on the disc surface; the spot is then polarized by an electromagnet from the other side of the disc. When read, the change in polarity changes the reflection of the (weaker) reading laser at that spot, and difference is interpreted as a data times, much like a magnetic hard disk, and are more durable and cheaper (per byte of storage capacity) than their magnetic cous-

ins. The CD-MO standard is defined in Part I of the Or­ange Book, but the technology never took off and has been replaced with CD-ReWritable (CD-RW).
CD-R This is a relatively ne w outgro wth of CD-R OM technology, whereby data can be easily recorded to a writable CD by a laser instead of being manufactured. This technology has found many uses with those who need to create limited numbers of discs for distribu­tion. The technology is “Write Once”, Once the data is recorded it’s permanent. CD-R discs, once recorded, are compatible with all CD players and CD-ROM drives. CD-R discs can hold up to 650Mb of user data, or up to 74 minutes of digital audio, just like regular stamped discs. See Gold Disc.
CD-ROM Acronym for Compact Disc Read-Only Memory. CD-ROM drives can only read the informa­tion contained on a CD - they cannot write information to it. The discs are created by pressing them from a stamper containing a mirror image of the disc. Their cost per a unit is low, and they are commonly used for the mass distribution of software and publishing of in­formation. CD-ROM Drive A peripheral device at­tached to a computer that allows it to read/play a CD disc. All CD-ROM players can also play back audio CD’s but require external head-phones or speakers to hear them. Some can be attached to amplifiers to func­tion like normal audio CD players.
CD-ROM/XA “XA” stands for Extended Architec­ture. CD-ROM/XA is an extension of the Y ellow Book standard, generally consistent with the ISO 9660 logi­cal format but designed to add better audio and video capabilities (taken from the CD-I standard) so that CD­ROM can more easily be used for multimedia applica­tions.
CD-RW Compact Disc ReWritable, a relatively new addition to the recordable CD arena. CD-RW discs are
77
DISCRIBE CD Mastering Software
the same formats and capacities of CD-R discs, but are fully erasable and rewritable. The CD-R W discs can be rewritten up to 1,000 times, but are not compatible with older (say, 12X or slower) CD-ROM drives, or consumer type CD players. Newer “Multi-Read” com­patible CD-ROM drives and DVD-ROM drives can read CD-RW discs.
CD-V Compact Disc V ideo. A disc containing CD-D A music as well as analog video. These discs can be 12 cm, 20 cm EP (extended play), or 30 cm LP (long play) CD’s. CIRC Cross-Interleaved Reed-Solomon Code­the first level of error correction used in ev ery compact disc, and the only one used for audio CD’s. It consists of two Reed-Solomon codes interleaved crosswise.

Constant Angular V elocity A rotation mode in which
78
Glossary
a disc spins a constant speed, with the result that the tracks nearest the center pass under the reading head at a lower speed that the tracks nearer to the outer edge of the disk. This is the approach normally taken in mag­netic disks, so the sectors on the disk are physically shorter near the center and longer near the edge of the disc. CAV is also used for Magneto-Optical discs and CD-R/RW discs (reading only)
Constant Linear Velocity A rotation mode in which the speed of rotation is variable, so that all data sectors pass under the reading head at exactly the same speed; the rotation rate of the disc is faster when the reading head is near the center of the disc, and slower as the reading head moves further from the center of the disc; sector size is constant. Used with Compact Discs for recording and slower speed reading/playing.
Cost-Per-Megabyte A measure of the expense in­curred per megabyte of usable storage received. The common formula is to divide the cost of the drive-and the case of the removable media, the cost of the media­by the number of megabytes. This measure alone ig­nores performance issues, which has a significant im­pact on the selection of storage method.
Cyclability A measure of how many times a CD-RW disc can be re-written. Currently, cyclabilty for CD­RW is set at 1,000 cycles (rewrites to any one sector)
Direct Overwrite (DO W) A method of recording new data onto a CD-RW disc directly o ver the existing data. This saves time since the disc does not need to be pre­erased prior to recording new data. Some Magneto­Optical systems are capable of DOW.
Directory In the logical format of a disc, a “branch” of the information tree containing other directories (sub­directories) and/or files.

DISCRIBE CD Mastering Software
Disc or Optical Disc Throughout this glossary, disc with a “c” is used for optical media, since that is the spelling used in the standards defining compact discs. Contrast with “disk”.
Disc-At-Once A method of recording a CD-R disc that is best suited for mastering a Compact Disc for repli­cation. With Disc-At-Once recording, the Lead-In is written first, followed by the data or audio tracks, and then the Lead-Out is recorded. In this way, the record­ing laser is never turned off and no “link” blocks are written to link the tracks, Lead-In, and Lead-Out areas, as occurs when a disc is recorded in Track-At-Once. See also Track-At-Once
Disc Image See ISO Image. Disk Hard disk or floppy disk or diskette. Refers to
magnetic storage media, as opposed to disc, which re­fers to an optical storage medium.
DVD Stands for Digital Versatile Disc, a high capacity disc that looks like a CD, but is capable of storing up to 4.7GB worth of data (or up to 130 minutes of MPEG-2 video with up to 8 channels of audio and 32 tracks of subtitles/menus). Higher capacity DVD discs are possible with double sided discs, and even discs with two information layers per side. DVD discs can only be read by players displaying a “DVD” logo (ex­ample: DVD-ROM drives & DVD-Video players). DVD will be available in several “formats”, including DVD-Video for distribution of consumer movies, DVD-R OM for computer data applications (including games & other multimedia content), and DVD-Audio for the ultimate music playback (specification not yet defined). DVD-RAM ReWritable D VD disc with a ca­pacity of 2.6GB or 4.7G, and using the Micro UDF logical file system. Similar to DVD+RW, this re-re­cordable DVD format is backed by the DVD consor­tium.

DVD-R Write once recordable version of DVD ha ving a capacity of 3.9GB or 4.7GB and using the Micro UDF logical file system. DVD-R discs are playable in DVD players and DVD-ROM drives, and DVD-R drives should be capable of reading standard CD­ROM, DVD-ROM, and DVD-Video discs.
DVD+RW ReWritable DVD disc & driv e system pro­posed by Sony , Philips, HP, Yamaha, & Ricoh as an al­ternative to DVD-RAM. This format provides 3.0GB or 4.7GB of data storage and affords a cleaner forward compatibility path with future DVD-R OM dri ves. The DVD+R W disc is a bare disc, similar to a CD-R W disc, and is compatible with standard DVD-R OM drives and DVD players. DVD+RW uses Constant Angular Ve­locity (CAV) for better performance than DVD-RAM. DVD+RW drives are also capable of reading CD­ROM, DVD-R, DVD-ROM, and DVD-Video discs.
ECC Acronym for Error Correction Code. In CD­ROM, a system of scrambling data and recording re­dundant data onto a disc as it is pre-mastered. On play­back, this redundant information helps to detect and correct errors that may arise during data transmission. See also Block Error Correction.

taining up to 98 audio tracks in the first session, and usually 1 data track in the second session. Enhanced CD came about as better solution for putting audio and data tracks on a single CD-ROM than mixed mode discs. With Mixed mode, the data and audio tracks re­side in a single session, and some CD players would try to play the data track, which comes out as static. With Enhanced CD, a regular CD player only “sees” the audio tracks in the first session, while a CD-ROM drive would be able to play the audio tracks and access the data in the second session.
Error Correction Code See ECC Error Detection Code See EDC FireWire A high speed serial interface that can link
different types of devices on one logical bus. Apple Computer is credited with the first implementation of FireWire on its G3 Macintosh computers. FireWire can be used to connect digital video cameras, hard drives, CD-R W dri ves, and personal computers togeth­er. Up to 63 devices can be daisy chained, and band­widths of up to 400 Megabits per second are possible today, and o v er 1 Gigibit per second is possible by the end of 2000. See also IEEE1394, & i.LINK

pre-formed track spiral, which the recording laser beam will follow when inscribing information onto the disc. This type of disc is therefore called pre-grooved. A translucent green or gold layer of recording material (organic dye) is laid on top of the polycarbonate, then a reflective layer of gold (hence the name “Gold Disc”). The usual layers of lacquer and label are ap­plied.

High Sierra Group The original group of twelve companies which met in 1985 to define a standard log­ical file format for CD-ROM. The group met at the High Sierra Hotel near Tahoe, hence the name “High Sierra”.
Hybrid Disc A disc as defined in the Orange Book de­veloped by Philips and Sony; such a disc may contain information written over more than one recording ses­sion. Used with Kodak’s Photo CD. Hybrid is also a generic term used to describe a disc with both ISO9660 and Macintosh HFS or UNIX data structures.
IDE Intelligent Drive Electronics. IDE has been the
83
DISCRIBE CD Mastering Software
standard interface for hard disk drives since the early 90s. Since IDE had some limitations (only 2 devices could be supported by a controller, and only supported devices with less than 500Mb capacity), Enhanced IDE (EIDE, also called AT API) was born. T oday EIDE is the standard storage peripheral interface used on PC computers to attach hard drives, CD-R OM dri v es, CD recorders, and DVD-ROM drives
IEEE1394 International standard for the high speed serial interface also known as “FireW ire” or “i.LINK”.

Lead-Out Area On a CD-R, CD-RW, DVD-R, DVD­RAM, or DVD+RW disc, a data area at the end of the disc (or session) that indicates the end of the disc/layer (or session) has been reached.
Logical File Format Translates the sector-and-mode view of a Compact Disc into a virtual “tree” of direc­tories and files, which makes it easier for both humans and computers to use the information on the disc. In this CD, for brevity , we often call it simply the logical format or logical file system.
Magnetic Hard Disk Sometimes called a W inchester disk, the generic term for this storage medium is “hard disk”, and it refers to the fixed magnetic storage devic­es supplied with almost all personal computers and workstations. Capacities range from 20 Megabytes to over 9 Gigabytes.
Magneto Optical (MO) The technology used by most rewritable optical drives. It uses a laser to heat magnet­ic recording media until its resistance to reversing its magnetic polarity falls at which time a small magnet reverses the field.
Mastering The process of creating a glass master from which Compact Discs or DVD discs will be repro­duced. Data is read from a tape (or CD-R/DVD-R disc) to a powerful modulated laser beam that “engraves” the corresponding pits into a photo-resistant surface.

computer data and CD-DA tracks. Usually, the com­puter data is all contained in Track 1, and up to 98 tracks of music are recorded on the following tracks.
Mode There are two recording modes for Compact Disc Read Only Memory (CD-ROM). In Mode 1, 288 bytes of each
sector are used for storing error correction code, and the remaining 2048 bytes per sector are available for user data. Mode 2, used in CD-I, CD-I ready, Video CD, PhotoCD, Enhanced CD, and other CD-ROM/XA applications, have 2 forms: Form 1 is similar to Mode 1, as it is also used to record data that requires error correction; Form 2 is used for recording information such as sound, images, or video which do not require such extreme precision. Since less error correction code is needed, more bytes in the sector can be devoted to information storage, resulting in a data area of 2336 bytes per sector.
MPEG Motion Picture Experts Group, whose name has been applied to the standard promulgated by the group for compression of full-motion video. MPEG-1 is a lower level of quality (352 x 240 pix els @ 30 fields per second) and compression, and is used for CD-I and
87
DISCRIBE CD Mastering Software
Video CD. MPEG-2 is a much higher level of quality (720 x 480 @ 60 fields per second), and is used for full length motion pictures and video distributed on DVD discs. The MPEG standard has been adopted by ISO.
Multi-Function Recorder A CD recorder capable of recording more than 1 type of writable media. For ex­ample, a CD-RW recorder can record CD-Recordable (CD-R) and CD-ReWritable (CD-RW) discs, as well as reading/playing CD-R, CD-RW, and regular stamped discs. Multimedia This term covers a v ast and vague area concerned with the integration of sound, video, images, and animation. Multimedia presenta­tions can be interactive, where the user makes deci­sions on how to proceed with the program, or it can be a linear presentation designed to run without user in­volvement.
Multi Read (MR) A certification that a CD-ROM drive or DVD-ROM drive can read the phase change CD-ReWritable (CD-RW) disc, as well as a CD-R or CD-RW disc that has been recorded using packet writ­ing. Multi Read also covers the playback of CD-R/CD­RW discs on DVD-ROM drives.
Multi-Session Originally developed by Philips and Kodak to facilitate distributing photographic images on CD-R discs. The concept is that new photographs could be added by recording a new data area (a ses­sion) on the disc. When played back, all the images in each session would be accessible as one logical vol­ume, the user would not realize the data was in sepa­rate recording sessions. This was later applied to general data storage on CD-R and CD-RW discs. A session occupies at least 15Mb of disc space, and therefore it’s not v ery efficient to record small amounts of data at a time.
OPC A procedure done by a CD recorder before re­cording on a CD-R or CD-RW disc to calibrate the la-

Orange Book The Philips/Sony specification for Compact Disc Magneto Optical (CD-MO), Compact Disc Write-Once (CD-WO, but commonly called CD­Recordable or CD-R), and Compact Disc ReWritable (CD-RW). The Orange Book is divided into three parts, Part I is devoted to CD-MO, which ne ver got of f the ground, Part II is the CD-R portion, and Part III is the CD-RW portion. The Orange Book specified how the recordable/re-writable discs and constructed and used by the recording/playback systems. All other CD formats can be applied to the recordable/re-writable discs through the Orange Book.
Packet Writing A method of recording on a CD-R, CD-RW, DVD-R, DVD-RAM, or DVD+RW disc where “packets” of data are recorded at a time as op­posed to “tracks” or “discs” at a time. The chief benefit of packet writing is that the CD recorder can start and stop recording at will, and so there is no more buffer underrun problems. However, packet writing can only be used to record data discs, all other formats must still use track-at-once or disc-at-once. See Track-at-Once and Disc-at-once.
PCA See Power Calibration Area Phase Change Optical recording technology that in-
volves changing the physical phase of the optical me­dia using a laser. The two states are Crystalline and Amorphous. Heating the media to a certain tempera­ture causes the phase to change to Amorphous (dark mark). Re-heating the same spot to a lower tempera­ture causes the spot to re-crystallize back to the Crys­talline state (clear). The Amorphous marks hav e lower reflectivity than the surrounding Crystalline lands, and have the same light scattering effects as pits and lands

The color books include the Red Book for digital audio (music discs), Yellow Book for CD-ROM, Green Book for CD-Interactive (CD-I), White Book for Video CD, and the Orange Book for the CD-Recordable (CD-R) and CD-ReWrit­able discs. See also Red Book, Yellow Book, Green Book, White Book, and Orange Book.
Physical Sector Described by the Yellow Book, each Compact Disc is divided into 270,000 physical sectors of 2,336 bytes each.
Pit The space between two lands along the data spiral of a Compact Disc or DVD disc. The “pits” on a CD­R, CD-RW, DVD-R, DVD-RAM, or DVD+RW disc are different from those on standard Compact Discs because they are not actual indentations but “mounds” (CD-R or DVD-R) or “marks” (CD-RW, DVD-RAM & DVD+RW) created in the recording layer by the la­ser beam.

the polycarbonate substrate for the recording laser beam to follow when writing data onto the disc.
Pre-Master The may be a tape, hard disk driv e, CD-R or CD-RW disc that contains data in the Compact Disc format. The data on a pre-master is recorded onto a master from which Compact Discs are then mass rep­licated.
Power Calibration Area (PCA) An area of a CD-R or CD-RW disc that is reserved for the CD recorder to calibrate the laser power for recording the disc.
Program Memory Area (PMA) An area on a CD-R or CD-RW disc where the information about the tracks and sessions on the disc as stored as a temporary T able of Contents (TOC). When the disc (or session) is final­ized and closed, the information stored in the PMA be­comes the TOC.
Random Access When data on a storage medium can be accessed randomly instead of sequentially. A close analogy would be in music - a cassette tape offers se­quential access because you have to wind through the tape to reach a certain part, yet a phonograph record would be random access because you could place the needle anywhere on its surface. CD-R and CD-RW, like hard disk drives and optical drives are random ac­cess devices.
Random Mode UDF Ability for CD-RW, DVD­RAM, or DVD+RW to randomly write, erase, and re­write any random sector on the disc. In earlier “se­quential” recording modes, sectors could only be re­corded in a track in ascending order, so that any one file or folder could not be deleted. The user could “vir­tually” delete the file/folder, but it w ould physically re­main on the disc until the whole disc was erased. Random mode allow a file/folder to be deleted and the free space it creates can be used immediately

Real-Time In Compact Discs, refers to the playing or recording time as these processes are actually taking place. Also refers to single speed (1X) recording or playback.
Red Book The original Philips/Sony color book spec­ification that describes the layout and physical format of audio Compact Discs. All other color books are based on the Red Book. Red Book provides for two layers of error correction code to detect and correct er­rors while the disc is being played. Up to 99 tracks are possible on a Red Book disc, with a total playing time of up to 75 minutes on 1 disc.
Region Code DVD titles, especially movies, are en­crypted with a region code. DVD players/drives are also assigned a region code, and only discs encrypted with the same region code as the player or DVD-R OM drive will play on that player/driv e. How it works is the world is broken down into 6 regions (for example, North America is part of re gion 1). Only discs intended for distribution in region 1 (encrypted with region 1 code) will play on a DVD player intended for distribu­tion (and configured) for region 1. This helps movie companies control the release of titles in different mar­kets around the world.
ReWritable Optical Storage A high capacity optical storage technology that operates much like a high­speed, very high capacity floppy drive - it allo ws users to write and erase data on a disc. CD-ReWritable (CD­RW), along with Magneto Optical (MO), D VD-RAM, and DVD+RW are all examples of rewritable optical storage.
Rotational Speed The speed at which the disc spins inside a drive. It’s usually measured in RPM (revolu­tions per minute).

laser power to a CD-R or CD-R W disc. Running OPC continuously monitors the laser power, and can adjust the laser power “on the fly” to compensate for dust, fin­gerprints, or other contamination on the disc. This en­sures a very consistent, robust recording.
SCSI An acronym for Small Computer System Inter­face, usually pronounced (“scuzzy”), which is a stan­dard computer peripheral interface which is used on Macintosh
computers, IBM-compatible computers, and worksta­tions to communicate with storage devices and other peripherals Up to 7 devices can be connected to a SCSI chain, and SCSI generally offers improved perfor­mance over EIDE (ATAPI) and USB. SCSI perfor­mance is par with i.LINK/IEEE1394
Seek Time This is a performance statistic which refers to the amount of time it takes the drive’s read head (or pick-up, in the case of a CD recorder) to find a piece of data on a disc. Seek time claims can be misleading though, as manufacturers can locate all the data to be found in one narrow band of the disc - reducing the dis­tance the pick-up must travel and shrinking seek times.•Session A complete logical v olume on a CD-R or CD-RW disc having a Lead-In area with table of contents, one or more tracks (data or audio), and a Lead-Out area. A session occupies approximately 15 Megabytes of space on the disc as overhead. See also Multi-Session.
TOC (T able Of Contents) Information on the number of tracks, their starting and stopping locations, and the total length of the data (or music) on a disc. If a disc has only one session, then there will be only one TOC. Multi-session CD-R, CD-RW, or DVD-R discs will have a T OC for each session on the disc, with referenc­es back to the previous sessions.

Track Adjacent bands of the data spiral on a Compact Disc. A Compact Disc (of an y format) may hav e up to 99 tracks.
T rack-At-Once (TAO) The most common method of recording a CD-R disc currently. Track-at-once simply means that one track at a time is recorded on the disc. Track-at-once is mostly used when recording Multi­session CD-ROM discs, each new session will contain at least 1 track. Track-at-once is mostly used for gen­eral data storage, and is not the best way to master a disc for replication. Disc-At-Once is the preferred way to master a disc for replication. Track-at-once writes the data (or audio) tracks first, then records the Lead­In area with the TOC, and then jumps to the end of the session to write the Lead-Out. See Disc-At-Once. Track-At-Once can also be used to record a CD-RW disc.
Track Relative Time A technique to determine the start and stop times of sound segments on a Mixed mode disc.
T ransfer Rate The rate at which digital information is transferred from a storage medium. For Compact Discs, Real time (1X) transfer rate is 150 Kilobytes (Kb) per second. 2X transfer rate is 300Kb per second, 4X transfer rate is 600Kb per second, and so on.
UDF (Universal Disc Format) A recently added log­ical format that is closely associated with ISO9660, but offers expanded flexibility for recording CD-R or CD-RW discs using packet writing. Like ISO9660, UDF is cross platform and discs created with UDF can be interchanged with PC, Macintosh, and UNIX com­puters. UDF can accommodate long file names, some­thing ISO9660 was very inflexible with.
Universal Serial Bus (USB) Easy to connect serial in­terface used on personal computers to attach lower

performance devices such as keyboards, mice, and some storage products such as lower performance CD­RW and floppy dri ves. Bandwidth is only about 1.2Mb per second (maximum), and around 600Kb per second sustained. Fast enough to record a CD at 4X. USB is attractive for attaching peripherals as ports are stan­dard on both PC and Macintosh computers, and is eas­ily “plug & play” installed as external devices.
White Book Specification for the V ideo CD dev eloped by Philips, Sony , JVC, and Matsushita. This specifica­tion uses the MPEG-1 video technology to store mo­tion pictures efficiently on a standard capacity Compact Disc. A V ideo CD is a Mode 2 CD-R OM XA format disc.
Winchester Disk When originally developed, the magnetic hard disk was named because the develop­ment project was called “Winchester”, and the first drive model was 3030. Later the generic term for this device came to be “hard disk”.
WORM An acronym for Write Once, Read Many; which is another type of optical storage that is similar to CD-R. Like CD-R, WORM is a write once technol­ogy where the data is permanently recorded onto the disc with a laser. Unlike CD-R, how-ever, WORM drives and cartridges are of a proprietary format and not suited for interchange.
Writable Optical Media This is kind of the umbrella term for all optical media that can be written or record­ed. It includes write-once technologies such as CD-R and WORM, as well as rewritable optical technologies such as CD-RW, MO, etc.
Yellow Book The Philips/Sony specification for CD­ROM discs based upon the Red Book standard. This book defines two sub-modes: Mode 1 & Mode 2; and provides for a third layer of error correction code over
