ASUS CD-R/RW Drive User’s Manual

I. INTRODUCTION

Introduction

The ASUS CD-R/RW Drive is a new generation half height 5.25” internal CD-Re­cordable/ ReWritable drive with the popular Enhanced IDE interface.

The drive is in fact a multi-function device, since it can be used as:

• Fast CD-ROM reader

• CD-Recorder, e.g., to record your own CD-ROMs or Audio-CDs

• CD-ReWritable device to use as your personal storage medium, by using

Incremental Packet Writing

The ASUS CD-R/RW Drive is the ideal tool for publishing large amounts of data in
compact form on CD. The new Incremental Packet Writing function will make this
drive attractive to the general desktop PC-user for personal data storage.

CD-Recordable discs can be recorded at the supported speed of your drive, and in
all standard formats, e.g., CD-Audio, CD-ROM (XA), CD-i and Video-CD. Since
these discs are recorded in accordance with the Orange Book (Part II) specification,
these discs can be played back on all compatible CD-players.

CD-ReWritable is a new feature that allows reuse of previously written discs by
rewriting portions or the complete disc in accordance with the Orange Book (Part
III) specification. These discs can also be recorded at the supported speed of your
drive in all standard formats.

Features

already been provided with a preformed track spiral into which the data will be
written during recording.

• On top of the green recording layer is a reflective gold layer and a protective
layer of plastic material.

The Additional CD-R/R W Area
of a CD-R and CD-RW Disc

The additional CD-R/RW area is divided into two areas:

• The Program Memory Area (PMA) which mainly contains the track numbers of
the tracks recorded with respective start and stop points.

• The Program Calibration Area (PCA). Disc space for the CD writer to calibrate
the laser energy needed for recording on the disc by means of a trial recording.

A Cross-section: Blank CD-R or CD-RW Disc

Next to the centre hole is an area for the mechanical clamping of the disc in the
player. Adjacent to this is the unrecorded area of the blank CD-R or CD-RW disc.

The Best Way to Create Your Own CDs
—With Re-usable CD-RW

• CD-ReWritable (CD-RW) gives you the opportunity to create your own
CDs, in the best and most cost-effective way. CD-RW is, in fact, the logi­cal extension of CD-Recordable (CD-R). Together, they give you the op­portunity to run the media that best suits the job in hand.

• CD-R W supports the recording of small packages of data, using incremen­tal packet writing in the universal (UDF) file format. As with floppy discs,
you have the option of writing a disc all at once, or building it up bit by bit

- and re-using the disc later for other data.

• CD-R W media can be rewritten hundreds, or even thousands of times. This
means that the overall running costs, for hardware and software together,
can be very economical indeed.

• CD-R W will greatly extend your personal short-term storage capacity , pro­viding space for large-volume files like Internet downloads, backups, and
hard disc dumps. It is also excellent for low-quantity multimedia applica­tions, from one-off disc testing to small-scale distribution.

Multiread: Making CD-RW Media Compatible with
CD-ROM and DVD-ROM

• CD-R W media reflects less laser light than the other CD media. To play all
CD media, drives must be able to adapt to these different reflectivities.

• For compatibility , drives need to do this in a standard way. They also need
to interface and interact with their host computer systems in a standard
way.

• That standard way is MultiRead. And any CD drive can play all CD media
—CD-Digital Audio, CD-ROM, CD-R, and CD-R W—provided that it sup-

ports MultiRead.

• What is more, MultiRead extends the same compatibility to DVD. All DVD
equipment that supports MultiRead will also be able to retrieve CD-RW
data. This means that you can go ahead now with storing valuable data on
CD-RW media, safe in the knowledge that it will be future-proof.

What is CD-Recordable?

• CD-Recordable is compact disc technology that allows the user to create
their own CD’s. This is done by means of a recording system that uses
“Write once” type optical discs and documented in the “Orange Book, Part
II” and a CD recording device that is connected to a host system.

T ypically , the host system is a personal computer that also contains record­ing software.

What is the Orange Book?

• The Orange Book is a document that describes the specification for CD­Write Once (CD-Recordable) technology.

• It defines both the physical structure and dimensions of a CD-R disc as
well as the use of certain portions of the recording surface:

• To record information (the Program area),

• T o calibrate the recorder laser power (Power Calibration area or PCA),

• T o record track information for all sessions (the Program Memory area

or PMA),

• To record the Lead-in Lead-out areas that preceed and follow , respec-

tively, the Program area.

• There are several “parts” to the Orange Book. Part II refers to CD-Record­able.

What does Orange Book-certified Media Mean and
Why?

• The Orange Book, Part II is the primary specification for CD-R media.
Accordingly, all CD-R media should meet the Orange Book criteria for
recordability and playback.

• Philips and Sony , the orginators of the Orange Book, provide Orange Book
certification of CD-R media.

What is Multisession CD?

The principal purpose of multiple sessions is to allow additional data to be appended
to a previously recorded disc.

NOTE: Some older cd readers can read only the first session of a multisession disc.

A session is defined as an area including lead-in, program data and lead-out.

• A CD-R recorder that supports multisession recording can write a disc that
will have multiple sessions linked together, each containing their own lead­in, program and lead out.

• Any multisession-supported CD reader can access the data, whether it was
written in the first session or a subsequent session.

Contrast this to the recording structure of a pressed CD-ROM or a CD-R written in
“Disc at Once” mode that contains just one lead-in area and one lead-out area.

What is the Recording Speed of CD-R?

The “speed” rating of a CD-Recordable/Rewritable determines how fast it can record
data to blank CD-R media.

Speed designators, such as “1X”, “2X”, “4X” and “6X” define multiples of the
original playback speed of first generation CD-ROM players:

• For a CD-ROM player or CD-Recordable/Rewritable, a 1X speed trans­lates to 153,600 Bytes per second. This is usually rounded down to 150 Kb
per second. Therefore, a “1X” recorder writes 150 Kb per second to the
CD-R media.

• Likewise, a “4X” recorder records at 600 Kb per second.

NOTES: 1. There are some variations in measuring speed, because there are recording

modes that provide more than 2,048 data bytes per block (audio is recorded
at 2,352 bytes per block).

2. Some CD-Recordable/Rewritables have a different reading speed than their
rated recording speed. For instance, a “4x4x32” CD-Recordable/Rewritable
can write at 4x speed and read back at 32x speed.

What is the Difference Between CD-R “Fixation” And
“Finalization”?

• Fixation is the process of writing the lead-in and lead-out information to
the disc. This process finishes a writing session and creates a table of con­tents.

• Fixation is required for a CD-ROM or CD-Audio player to play the disc.
Discs which are “fixated for append” can have additional sessions recorded,
with their own session lead-in and lead-out, creating a multisession disc.

• When a disc is “finalized” the absolute lead-in and lead-out for the entire
disc is written, along with information, which tells the reader not to look
for subsequent sessions.

This final table of contents (TOC) conforms to the ISO 9660 file standard.

What is “Disc At Once”?

• Disc at Once is a writing mode that requires data to be written continu­ously, without any interruptions, until the entire data set is transferred to
the CD-R.

• The lead-in, program and lead-out are written in a single event. All of the
information to be recorded needs to be staged on the computer’s hard disc
prior to recording in the Disc at Once mode.

• This mode is usually preferred for discs that are sent to a CD-ROM repli­cation facility when CD-R is the source media.

ASUS CD-R/RW Drive User’s Manual 31

Glossary

VI. APPENDIX

• Recording in the Disc at Once mode eliminates the linking and run-in and
run-out blocks associated with multisession and packet recording modes,
which often are interpreted as uncorrectable errors during the glass mas­tering process.

What is “Track At Once”?

• Track at Once is a writing mode that allows a session to be written in a
number of discrete write events, called tracks.

• The disc may be removed from the writer and read in another writer (given
proper software) before the session is fixated.

The written sessions contain complete “tracks” of information.

What is “Incremental” or “Packet” Writing?

• Track at Once writing is a form of incremental write which mandates a
minimum track length of 300 blocks and a maximum of 99 tracks per disc.

• A track written “at once” has 150 blocks of overhead for run-in, run-out,
pre-gap and linking. Packet write, on the other hand, is a method whereby
several write events are allowed within a track, thus reducing the over­head.

These “packets” are bounded by 7 blocks for run-in (4), run-out (2) and link (1).

What is the Difference Between a “Multisession” Disc
and a “Multitrack” Disc?

• A “session” is a unity on a CD which is bounded by lead-in and lead-out. A
session contains one or several (up to 99 per disc) tracks.

• There are two types of tracks. A Red Book audio track is usually written in
disc at once mode along with several other tracks in one session.

These tracks have index numbers in the subchannel which differentiate
one from the other and which allow selective playback.

• The other type of track is the incrementally written type described above.
