1 Introduction
1.1 CD-Recording as a New Technology
At the beginning of the 1980's, the CEO of a large electronics company which was intensively driving the development of the digital compact disc (CD) - used at that time primarily for music - was asked if there was truly a market for these little discs. Since then, the question has provided its own answer. Analog black records can now only be found at flea markets, and in most music stores the space for cassettes is less and less to make room for CDs.
Its memory capacity of 650 MB and the excellent price-performance rela­tionship, combined with problem-free usage and data security, made the data processing world sit up and take notice of the new medium. At the same time, people were really only thinking of a read-only technology (ROM = Read Only Memory) in 1985.
In 1989 a process was developed with which a CD can be directly written by means of a laser beam. The way for the self-creation of CDs was thus opened. At the moment you can distinguish a CD recordable from the non­writable by their gold or green burning side. Massproduced CDs are silver, and they cannot be burned on a CD-recorder.
With the passage of time, the self-creation of CDs to meet individual needs has been made easy and economically feasible thanks to improved hardware and practical software. You have just such a product in your pos­session right now: Thanks to its user-friendly interface and optimized proc­esses, Nero - Burning Rom makes it possible for you to easily and quickly create your own CDs.
Introduction
1.2 Applications for CD-Recording
The CD is an ideal medium for the distribution of information of any kind (text, images, sound, data and programs). Along with relatively low production costs, it provides high memory capacity with direct access and a long life span, and is thus without competition at this time, even when you only have low production numbers. For this reason, a majority of all PCs today are already equipped with a CD-ROM drive.
The self-created CD opens a wide range of application possibilities:

Chapter 1
Let's assume that you, as a program developer, have generated a test version of your software and copied it directly to a CD-R. You may immediately test it for functionality and performance and then pass it on to the pressing op­eration to have it copied. The same is true with electronic books and CBT applications (Computer Based Training), for example.
Until today, magnetic tapes and streamers were generally employed for data security and for hard drive back-up, while microfilm and microfiche were widely used for archiving of data. Access to data stored in this manner is complicated and relatively slow. Here the CD represents an attractive alter­native because you can access your data with more convenience and speed.
If you want to archive your Photos in digital form, a CD is ideal for this, be­cause it can handle the large file sizes. For example Photo-CDs have an ap­plication in the archiving of medical image data. Suitable data compression technologies make it possible to store entire films on Movie CDs.
For music lovers, the self-creation of personal Audio-CDs should be
among the most fascinating possibilities offered by CD-Recording. With this technology, you could compile your own entirely personal "The Best on CD" list, for example.
Speaking of that: The protection of intellectual property is guaranteed by national and international laws and regulations. Before you write data which is not yours onto a CD, you must therefore check into the legality of making the copy. The creation of copies of outside-sourced data is usually allowed only under specific conditions, or not at all. The responsibility for this in any case is entirely yours.
1.3 Layout of the Manual
This manual consists of a total of seven chapters which are supplemented by an Appendix and an extensive glossary.
You have just finished reading Chapter 1.
Chapter2 describes the installation of Nero with Windows.
Chapter 3 presents a simple example to show you how to create your
first CD.
Chapter 4 covers the basics of CD-Recording.
Chapter 5 will familiarize you with Nero in detail. You will learn more
about procedures, the individual windows and the actual writing or burn process there.
Chapter 6 is a step-by-step description of how you can create and write an ISO compilation, an Audio-CD or an image file.
Chapter 7 contains the Nero Reference. The indiviual menu items are systematically explained there.

2 Installing Nero
In this chapter, you will find out which components you need for CD-
Recording and how you install and configure Nero with Windows 3.1x,
Windows NT and Windows 95.
2.1 System Requirements
2.1.1 Hardware Requirements
As the minimal configuration for all Windows operating systems, you
must have: A PC with a 486 processor or higher and speed of at least 33 Mhz, a minimum of 8 MB RAM and an SCSI Host Adapter with WINASPI support.
The PC must have a CD-ROM drive in order to install Nero. If your CD-
Recorder is recognized as a CD-ROM drive when running with Windows, you may also use the recorder. Up to now, Windows 95 has supported all of the drivers which are required for this. You may experience less success with Windows 3.1x.
Your hard drive should be as fast as possible. The access time should be under 19 milliseconds. The necessary transfer rate from the hard drive to the recorder depends on the speed with which your recorder can write. If you have a 1x recorder, we recommend a transfer speed of at least 1 MB/second, and correspondingly 4 MB/second with 4x. Otherwise the data are not con­tinuously transferred to the recorder; the result can easily be a buffer under­run condition, the "worst possible scenario" in CD-Recording.
For Nero, you need approximately 4.8 MB of hard drive space.
Installing Nero
2.1.2 Overview: Components for CD-Recording
You will require the following components for CD-Recording:
- an SCSI-Host Adapter with a power cable,
- a CD-Recorder (either an internal or external device) and a terminator as required (if not installed internally),
- you already have the recording software (Nero - Burning Rom),
- and, of course, you will need CD-Recordables.
You can find out which CD-recorders are currently supported by Nero in
the Appendix covering Supported CD-Recorders , or you can get this infor­mation from your supplier.

Chapter 2
2.2 The Installation
2.2.1 Installation of the SCSI Host Adapter
Install the SCSI Host Adapter according to the manufacturer's instruc­tions. Don't forget to also install the software for the SCSI Adapter. If neces­sary, you must also install the ASPI Manager for Windows which is supplied with your SCSI Adapter. And finally, you must restart your PC.
Caution: Not all SCSI Host Adapters support WINASPI. You must therefore make absolutely sure when you buy your adapter that it supports WINASPI.
2.2.2 Installation of the CD-Recorder
Please refer to the installation instructions supplied with your recorder for detailed procedures.
Caution: If you only have one recorder connected to the SCSI Adapter or if your recorder is the last SCSI device connected, then you must gener­ally provide a terminator for the open SCSI plug on the recorder. Some re­corders have built-in termination. Again, you will find information on this subject in the recorder manual.
Don't forget to plug in the power cable.
If driver software is provided with the recorder that enables you to also use it as a CD-ROM, install the software.
Your recorder is now ready for operation. Restart your PC now.
Caution for an external recorder: Switch the recorder on first, and then the PC. If you do not follow this sequence, the recorder will not be recog­nized by the operating system; you will have to restart the PC at some time before you want to write to a CD.

2.2.3 Installation of Nero
You can configure Nero without any problems by using the installation
program. For the setup, carry out the following steps, corresponding to
the operating system you use.
2.2.3.1 Windows 95 and Windows NT 4.0
1. Insert the Nero - Burning Rom CD in the CD-ROM drive.
2. In the Start Menu under Run, select setup.exe on the Nero CD.
3. The Installation Program will guide you through the subsequent
steps. Just follow the instructions as they appear on the screen. You will be asked to enter such information as your name, your company and the serial number of the CD. You will find the serial number on or in the Nero package. You then have the option of choosing between
different setup types. After completing the installation, you can start Nero immediately.
2.2.3.2 Windows 3.1x
1. Insert the Nero - Burning Rom CD in the CD-ROM drive.
2. Select the CD-ROM drive in File Manager.
3. Then select the setup.exe program on the Nero CD.
4. The Installation Program will guide you through the subsequent
steps. Just follow the instructions as they appear on the screen. You will be asked to enter such information as your name, your company and the serial number of the CD. You will find the serial number on or in the Nero package. You then have the option of choosing between different setup types. Finally, you will need to enter the program group. After completing the installation, you can start Nero immedi­ately.
Congratulations! You have completed the installation of your Nero. Now
go to the Quickstart in Chapter 3 in the manual to find out how to write your first CD.
When you start Nero, the system preferences will be checked to ensure
that any preference settings which could initiate a message, thereby inter­rupting the burn process, are deactivated. This check is performed every time you start Nero, and the preference settings concerned are changed accord­ingly if you accept them and the PC is then restarted.
Installing Nero
2.2.4 Uninstalling Nero
If you are using Windows 95, Nero can be uninstalled, if necessary. Select
Nero from the Start Menu under Setttings/Control Panel/Add-Rem ... Pro-
grams, and select Remove. This operation will delete all Nero program files and will remove Nero from the Start Menu.
With Windows 3.1x, simply delete the Nero programs and any Nero pro-
gram groups which might exist in the File Manager.
11
3 Quickstart
After you have successfully installed Nero, you can begin your first job
with the recording software. In this chapter, we will use a simple example to show you how you can create a CD with Nero.
We will assume that you have installed Nero with Windows 95. You can
now open Nero through the task bar and the Start Menu. You will find the default installation for the program under
START > Programs > Nero - Burning Rom. Open Nero by clicking on it in the Start Menu. The following illustration shows the options window for a New Compila-
tion, which is the default window after Nero is started.
Quickstart
The dialog box
New Compilation
In a brief summary, the entire process for the creation of a CD may be de-
scribed in the following steps:
1. Creating a Compilation. In the Compilation, you determine which files
will be written on the CD.
The next two steps are for the only purpose of avoiding a possible
buffer underrun.
2. Determining Write Speed, also called the Speed test. This test is where
the maximum possible write speed is defined. If a slower speed is meas­ured in the Speed test than provided by the current setting, the speed setting is correspondingly reduced. This test should be performed before every simulation - or before the burn process, when there is no simula­tion.
13
Chapter 3
3. Simulation of the Write Procedure: Here, the data of the compilation
are transferred to the CD-recorder, but the laser beam does not write the data onto the CD. In this way it is determined whether you can ex­pect everything to run without problems during the burn process.
4. Burn process (Write process). You simply make sure a recordable CD
is correctly inserted and then press the Write button, provided of course the write speed test and simulation were successful.
3.1 Create a New Compilation
In the New Compilation dialog box, click on the CD-ROM compilation type (it doesn't matter which property sheet is currently activated). Leave all of the default options as they are. Then, in the upper right of the same win­dow, click on the New button.
The Compilation window will open. This window consists of two panes. In the left window, replace the file name NEW (in the upper left next to the CD icon) with HELLO.
In the right window, you will see the Nero file browser. The selection of the data which you want to write onto the CD is very simple with the browser. For your first attempt to write a CD, select the file "Hello.txt" from the file browser in the directory [Drive name]:\Programs\ahead\Nero (if you have accepted the suggested target directory during installation) and drag it into the left compilation window. Then activate it by clicking on it some­where.
Now save the compilation by clicking on the floppy disk icon in the tool­bar. The Save window will open. Type in the file name HELLO and then activate the Save button. Your first compilation file is now complete.
14
3.2 Determining Maximum Write Speed
Click on the icon for Write CD in the toolbar. The Write CD window is displayed with the Burn property sheet. The boxes for Determine Maxi-
mum Speed and Simulate are already selected in this window. Click on the Write selection box at this time. You may leave all of the other options with
their default settings. Confirm your selection by clicking on the Write button.
In the following illustration, you see the Write CD dialog box with the Burn property sheet and the selected options.
As the first step, Nero will now determine the maximum possible write
speed and then transfer this value into the Write Speed field.
Quickstart
The dialog box Write CD
3.3 Simulation of the Write Procedure:
The execution of this step was already set by the previous selection of the
Simulate box. Nero now simulates the burn process in order to test whether the actual burn process will also run without any problems. Nero will inform you when the simulation has ended. With many recorders, the CD will be ejected. This means that, depending on the recorder, it might be necessary to either re-insert the caddy or to close the CD drawer.
3.4 The Burn Process (Write Process)
You have already been prompted above to select the Write control box.
By doing this, the burn process is performed immediately after the simula­tion. Nero will now begin the entire writing procedure with all of the prese­lected phases.
During this process, a status window is opened (refer to the following il­lustration) which provides you with different information during writing. The current compilation is displayed in the upper pane of the window. The phase which is running and its result is shown in the center pane. Below this, you will see a progress display for each process.

Good job!
The end of the writing process is indicated by an information box.
You have just created your first CD-ROM.

Fundamentals of CD-Recording
4 Fundamentals of CD-Recording
CD-Recording is a relatively new technology. An explanation of new terms is therefore just that much more important. In this chapter, along with the most important fundamentals of CD-Recording, we will introduce you to the important terms and their meaning.
4.1 The Rainbow Books
Knowledge of the most important standards is necessary for a basic un­derstanding of CD-Recording. The first standard was defined in 1980 by Sony and Philips. It was published in a book with a red cover. Subsequent definitions followed this style, and each used a book cover with a different color. As a result, this series of standards has also become known as the Rainbow Books.
The family of Rainbow Books is being expanded constantly, including new versions of those already in existence which are published in order to keep up with new developments. For example, modifications were made in the Red Book in order to improve the play-back reliability of recordable CDs, which are actually described in the Orange Book.
4.1.1 Red Book
The first CD standard was known by the name "Compact Disc Digital Audio" (CD-DA). It describes the way music CDs, which may be played back by typical CD players, are produced.
However, even the name "Compact Disc Digital Audio" is not exactly correct. Among other things, the fundamental structural principles of all CDs and their corresponding play-back devices are described in this standard. This is because the structure and the essential elements of all CD formats are the same.
The Red Book defines the scan system at its lowest level, building from there to the EFM (Eight-to-Fourteen-Modulation) modulation process, a method for the synchronization and storing of control information (the length of the title, for example) and the CIRC (Cross Interleave Reed-Solomon Code) procedure for correcting errors. With the help of this process, the CD can even be played back when it is dirty or scratched.
It is only at the highest level - and only this level is truly specialized in mu­sic - that it is defined how music is encoded on a CD (CD quality): 44.1 kHz, 16 bit stereo.
17
Chapter 4
4.1.2 Yellow Book
In 1984 - for years after the first standard - the Yellow Book followed. This standard also originated with Sony and Philips. At the same time, the computer began to win the field. The significance of the CD as a storage medium for program files or applications for PC use was recognized very quickly. Thus, the CD-ROM was born.
Two further track types are defined in the Yellow Book, which have been designated as Mode 1 and Mode 2 (originally only defined with CD-I). Mode 1 is used for pure CD-ROMs. It always employs an additional code for error recognition and correction in order to ensure that scratches or manufacturing defects do not have any influence on the accuracy of the computer data.
Mode 2 is used with CD-ROM/XA (CD-ROM eXtended Architecture) and CD-I (Compact Disc - Interactive, see below), for example, and can be used for compressed audio data, videos, images and also for other types of data, whereby the differing types of data may occur within a single track. In addition, there is a differentiation between Form 1 and Form 2 sectors. In Form 1 - as with Mode 1 - a supplemental error recognition and correction code is used. It is only the arrangement of the data that is somewhat differ­ent. Form 2 does not make use of this additional protection. It is therefore only suitable for data in which errors do not necessarily create an interference (for example, with audio data).
A process which describes the way tables of contents for computer data are filed on a CD is not defined in the Yellow Book. The most frequently used method is defined in ISO 9660 and is supported by most operating sys­tems (Macintosh OS, MS-DOS and Windows, and also UNIX, for example).
4.1.3 Green Book
After three more years had elapsed, the next standard was introduced ­the Green Book. This standard describes the CD-I (Compact Disc - Interac­tive) and an operating system which is known as CD-RTOS. The specifica­tion for the CD-I Bridge was also published in the Green Book. Both stan­dards represent an extension to the Red and Yellow Books, and they are based on ISO 9660.
While the Audio-CD is only suited for music and the CD-ROM was de­veloped only for use with a computer, the CD-I is aimed at the consumer market, although it has not achieved any wide-spread use there, except in one specialized form: the Photo-CD.
4.1.4 Orange Book
Most CDs are of the Read Only type (can only be read, and not written to). The Orange Book Standard describes various processes for writing data onto a CD, which in the case of the CD-Recordable is also known as burn-
18
Fundamentals of CD-Recording
ing. The Orange Book also originated with Philips and Sony and was first published in 1991. The standard is divided into three main sections:
Part I describes the Compact Disc - Magneto Optical (CD-MO), also known as the Hybrid-CD. The CD-MO contains an internal recording area which is produced similar to the typical CD. Externally, there is an area which can be read magneto-optically, and which can be written to more than once. However, this area cannot be read by a normal CD scanner.
Part II describes the Compact Disc - Recordable or Compact Disc - Write Once (CD-R, CD-WO). This CD may also have an internal area which is produced in the typical manner. Contrary to the CD-MO, however, the ex­ternal area is created in such a manner that it may be played back by any CD reading device. Generally, a CD-R possesses only this external area.
A CD-R may be written either as a whole or partially in several separate procedures which are known as sessions. One-time writing is described as a single session, while more than one writing is known as a multi-session. There are now also traditional CDs (silver) which are structured as multi­session CDs.
Part III is still in the standardization phase and describes the CD­ReWritable (CD-RW, formerly CD-Erasable). In contrast to the CD-R, this CD is not limited to just one writing, but may be erased and re-written as often as desired. Nonetheless, the CD-RW cannot be read by every tradi­tional CD reader, but rather only by those which are specially designed for CD-RW (known as CD-RW enabled CD players). It will be interesting to watch the future development of this technology.
4.1.5 White Book
The second-most recent standard is known as the White Book. It stan­dardizes the video-CD. A video CD can store over 70 minutes of playing time through the compression of the video data (with MPEG 1). The quality is about the same as that of a VHS video recorder. It is not adequate for true movie quality with Dolby Surround. It will probably not be until the next generation - the DVD (Digital Versatile Disc, also frequently and incorrectly called Digital Video Disc) with its even greater memory capacity - that this type of quality will be achieved.
4.1.6 Blue Book
This is the most recent standard and was established in 1995. The Blue Book describes the Enhanced Music CD, often called merely CD-Enhanced, CD-Extra or simply by its logo, CD-Plus or CD +. The enhanced Music CD is always a multi-session CD, or - to be more precise - a two-session CD. The first session contains audio data as defined by CD-DA (Red Book), the second contains a CD-ROM (Yellow Book). This means that information other than audio data may also be stored on one medium.

Chapter 4
4.2 Definition of Concepts
4.2.1 Tracks
Data items on a CD are not stored in concentric circles, as one might at first think. They are rather arranged in an extended spiral-shaped line whose origin is at the center of the CD. The line runs from the inside to the outside. Those sections on the spiral on which data items are located are called tracks. Up to 99 tracks may be stored on an Audio-CD. One track generally corresponds to one piece of music on the CD.
4.2.2 Sectors
The track itself is made up of units called sectors. A sector contains 2352 bytes, of which - depending on the type of CD used - a different number may be used for user data. The sector generally consists of a header, synchroniza­tion bits and user data. It may also have error recognition and correction data. To read a sector, a drive with single read speed requires 1/75th of a second.
4.2.3 Table of Contents
The initial area of the CD is physically located at the inside of the CD surface and is approximately 4 mm wide. It contains the Table of Contents of the CD (TOC) and other information about the CD, such as the name, the author or the date of the CD.
4.2.4 Single-Session, Multi-Session
The term multi-session practically speaks for itself. A multi-session CD was produced in several sessions, that is, recording procedures. The individ­ual sessions may have been written at random time intervals.
One session consists of at least one track.
A single-session CD is created in only one session, as the name implies. Audio-CDs are almost always single-session CDs, while CD-ROMs or Photo-CDs consist of one or more sessions.
4.2.5 Disc At Once, Track At Once
Today, we differentiate between two different recording technologies with CD-recorders: Disc At Once and Track At Once. Newer recorders generally support both technologies, while older devices frequently can only handle Track At Once.

Fundamentals of CD-Recording
For a recorder with Track At Once, every track is written separately. Therefore, pauses are unavoidably created between the tracks which cannot be influenced by the recording software. In contrast to this, with Disc At Once, the entire CD is written in one procdure, which allows more freedom for the recording software, but at the same time prevents subsequent modifi­cations. For many formats (Audio-CD) Disc At Once is more logical, since unnecessary pauses can be avoided, while Track At Once is generally used for multi-session CDs.
4.3 Recording Formats
We will give you an overview of the most important recording formats in the following sections.
4.3.1 Audio-CD
In 1980, the Audio-CD was the first medium for storing information on a CD. The corresponding requirements are described in the Red Book. All CD-ROM drives typically available in the marketplace can also read Audio­CDs.
4.3.2 CD-ROM
It is impossible to imagine today's PC world without the CD-ROM. The technical foundations are exactly the same as with the Audio-CD, except that they have been extended by an error-correction process. Thus computer data may also be reliably processed on a CD-ROM drive.
4.3.3 ISO 9660
The logical structure of a CD-ROM is established by the ISO Standard
9660. Right after the publication of the Yellow Book Standard, the so-called High-Sierra format was developed which was the forerunner to ISO 9660 and provided its basis.
ISO 9660 describes how data items are to be organized on a CD. Among these are the rules which limit the the number of levels in the directory structure or the length of the file names. ISO 9660 is supported by most of today's common operating systems (Macintosh OS, MS-DOS, Windows, Unix). Most CDs correspond to this standard. It is only in the Macintosh environment that HFS CDs have established themselves as alternatives to this standard.
In order for an operating system to read a CD which was created as de­fined by with this standard, software is required which can read ISO 9660

Chapter 4
files. For a computer running MS-DOS or Windows 3.x, the corresponding application is called MSCDEX.EXE. This is a driver which will ensure that the CD and the CD-ROM drive can communicate with each other. The driver must be loaded in both the AUTOEXEC.BAT and CONFIG.SYS system files separately. Windows 95 and the Macintosh operating system can both work with a CD as a standard feature.
ISO 9660 defines a directory structure which is designed from the outset in such a way that it can be used on as many different systems as possible. Therefore there are also stringent rules as to what file and directory names are allowed:
In a file or directory name, only the capital letters A through Z, the num­bers 0 through 9 and the underline character may be used. The file name must contain exactly one dot, which comes between the actual name and the file extension. The name and the extension may not be missing at the same time. The maximum length of a file or directory name may not exceed 31 characters.
Because many operating systems (MS-DOS, Windows 3.x) are not capa­ble of handling 31 characters, ISO 9660 defines a total of three levels of compatibility: Levels 1, 2 und 3:
For a CD-ROM as defined by Level 1, the following limitations are ob­served:
The file name may not be longer than 8 characters.
The file extension may not have more than 3 characters.
Directory names may consist of a maximum of 8 characters.
A CD-ROM as defined by Level 2 does not have any limitations for file or directory names, but a file may not be fragmented.
However, this limitation does not exist at Level 3. For example, Level 3 may be used for incremental backups when only parts of a large file have been changed. It is not necessary in this case to completely re-write the entire file. Instead, you can continue to use the old parts of the file already on the CD which are still valid.
There are expansions for many operating systems which attempt to store additional information in an ISO directory while not interfering with other systems. Examples of these are the Rock-Ridge-Expansions for Unix- Systems and the Apple-ISO Expansions. Joliet, which is defined by Micro- soft, has significance here. It provides a second, complete directory structure in Unicode and is currently being used by Windows NT and Windows 95.

4.3.4 Mixed-Mode CD
The Mixed-Mode CD contains a data track (CD-ROM as defined by the Yellow Book) and one or more audio tracks (CD-DA as defined by the Red Book). The Mixed-Mode CD has the advantage that the audio data can be made directly audible with the help of earphones or an amplifier (if they can be connected) without the requirement for a soundcard or a processor insert.
Fundamentals of CD-Recording
The synchronization of sound and other data do present a problem. This problem, however, is eliminated by the CD-ROM/ XA. Another problem is that old CD players occasionally attempt to play the data track back as audio information, which can cause unpleasant noises and - if the noise level is high enough - may lead to the destruction of the loudspeaker. This problem is eliminated by the Enhanced Music CD.
4.3.5 Enhanced Music CD
The Enhanced Music CD is a combination of an Audio-CD in the first session and a CD-ROM in the second session. The CD-ROM must contain a directory as defined by ISO 9660 and certain specified files. Beyond that, any other kind of data may be stored on it.
Much to the regret of the experts, the correct designation - Enhanced Music CD - has not managed to catch on for this format. Along with En­hanced Music CD, the terms Enhanced CD, CD-Extra or CD Plus are also in use.
4.3.6 Photo-CD
The CD-I (Compact Disc Interactive) is defined in the Green Book. Un­fortunately, CD-I is not quite CD-I. There is a wide range of applications for CD-I. Although in theory every CD-I should contain a program for playing the respective CD-I, this is not supported very well by many players. The most important application of the CD-I is the Photo-CD, which is not only capable of reproduction by CD-I or Photo-CD players, but can also be proc­essed by many computers, such as the Macintosh.

5 Nero
In this chapter you'll get better acquainted with Nero. You will learn the basics about how Nero works in the compilation of files. The user interface with its different windows and the burn process are also described here.
5.1 Basic Process
With Nero, the creation of a CD-ROM or an Audio CD is relatively sim­ple. First, you'll need to decide which files should be written onto the CD. Then you can give your undivided attention to the compilation. A compila­tion is created with Nero by the drag & drop method. Here, you'll select the files which you want from the File Browser and then drag them with the mouse into the compilation window. There, you can arrange your files in any way you wish or even insert new folders. The advantage here is that this ar­rangement does not have any influence on the physical file structure on the hard drive.
After the compilation is arranged the way you want it to be, you should run the speed test. This test checks the access speed to the hard drive, or to the partition where the files which you want to be written are located. De­pending on the results of this test, a speed for the simulation will be recom­mended. The simulation which will now follow (and it should always fol­low!) assumes this test result. By doing this, errors which might otherwise occur during the burn process may be detected and corrected. After a suc­cessful simulation, you can be relatively confident that the compilation you have created can also be written. The burn process itself takes place as the last step.
Nero
5.2 Terms and Concepts
During the preparation of data for the burn process, Nero follows the principles of a Virtual Image File, as it is known. This file is a reference to all of the files which are to be written onto the CD during the burn process. We call this the compilation, and the writing process which comes next is performed in a process known as 'On-The-Fly'. Every compilation is stored as a compilation file. The name of this file will appear in the bar above the compilation window. It doesn't have any influence on the name of the CD which is to be created. With a CD-ROM, we refer to this as a CD-ROM compilation, and an Audio-CD is called an Audio-CD compilation. Along
25
Chapter 5
with the file references which are to be written, a compilation contains addi­tional necessary information which is written onto the CD.
The term session defines a connected or related writing process. We dif-
ferentiate between single-session and multi-session CDs. Multi-session CDs are written in more than one burn process.
The name of the data medium (generally known as the volume label)
relates to the entire CD. This is the name you will find when you look for the CD, when you display the CD through the Explorer, for instance.
5.3 User Interface
Nero title bar Compilation window menu bar Browser window title bar of icon bar title bar of
compilation File Browser
The Nero interface
status bar
This interface is a Multi-Document Interface, or MDI, for short. With
MDI, there is a frame program which provides an outer window. This outer window continues as long as Nero is active. The menu bar, the toolbar and also the status bar are located here. Within this outer window, any number of "smaller" windows can be opened. By manipulation with the mouse, these windows can be changed in their size and location in any way you wish.
26
5.3.1 Title Bar
In the title bar, you will find the Nero system icon on the left, next to the product name. To the right of that you'll see the name of the current open file, and on the far right the three additional buttons which every Windows 95 application has.
If you click on the system icon in the upper left, the system menu field will open. You can perform different actions through this menu. On the other hand, if you double-click the symbol, the entire application is closed.
With the system menu, you can give commands to RESTORE, MOVE, change SIZE, MINIMIZE, MAXIMIZE and CLOSE.
Nero
In the right-hand corner of the title bar, you will find the three buttons which provide for dimensioning of the main window. These buttons are typi­cal of all Windows 95 applications. The left button is the symbol for the command to MINIMIZE. It is actuated by the mouse. A simple click is all it takes, and the window is then represented only as a small symbol in the task bar. In this way, you can easily put Nero aside and work with a different application. Nero continues to be active and the contents of the window aren't changed in any way. With the middle button, you can give the com­mand for the FULL DISPLAY or maximize. This is represented symbolically by a single small window or two windows that are overlapping. When this button shows a single small window, a click on it will fill the entire screen with Nero's main window. When it is two overlapping windows, a click will reduce the main window so that it only fills part of the screen. On the far right is a button with an X. When you click this button Nero is closed. If changes have been made to a compilation, a message box will be displayed in which you can decide whether the changes should be saved or not. The func­tions just described are just the same for other windows within Nero.
You can also change the size of the window if you use the mouse to dou­ble click on the title bar. If the window was a full screen, it will be reduced after the double click. Just the reverse, if the window was reduced, a double click maximizes it.
Other options are available to you for individually changing the size of the window:
Window borders can all be dragged to size the window in any direction
(down/up or right/left).
27
Chapter 5
If you "grab" the window at a corner with the mouse, you can change its
size by dragging it to the height or width you wish.
If the window is not a full screen on the desktop, it can be moved with the mouse. Just click on the title bar, hold the left mouse button down and you can drag the entire window into the position you want.
5.3.2 Menu Bar
As is typical with Windows programs, you will find the menu bar below the title bar. With Nero, there are a total of six menu items here. Each menu item represents a specific group of options, each of which carries out a spe­cific function. In order to access the options within a menu item, you must first open the menu. This is done by clicking on the menu item in the bar with the mouse. The menu selections are displayed. In order to activate the func­tion, place the mouse pointer on the desired menu option and click on it.
You may also use the ALT key to do this. When you do this, the FILE menu is highlighted as the default. Using the cursor, you can then select the desired menu item and then press the Enter key. The menu selections are displayed. You can move to the individual menu commands with the cursor. Press the Enter key again in order to open the corresponding function. You can also use the keyboard in order to invoke a menu item directly by holding down the ALT key and pressing the underlined letter of the menu item. For example, the keyboard combination ALT + R opens the CD-Recorder menu item directly.
The menu bar contains the following items:
28
File In the FILE menu, you will find the typical commands
such as OPEN, CLOSE, PRINT and EXIT. In addition, there is a command to WRITE CD and a command to retrieve detailed information about your compilation.
Edit The EDIT menu provides familiar menu items such as
Copy, Paste, and others.
View With this menu, you may determine which toolbars will
be displayed as defaults and how the contents of the Nero windows will be displayed. You may also activate an additional File Browser.
CD-Recorder In this menu, you will find instructions which concern
the CD-Recorder and the CD which is inserted into it.
Window You will find commands here which are typical to Win-
dows, such as the way the individual windows are ar­ranged.
