Cdrdao - Write audio CD-Rs in disk-at-once mode
===============================================================================
This file contains some additional information. See the manual page for usage
of the tool.
Please use the write simulation mode (command 'simulate') when trying this
program the first time on your system. This will detect problems or
incompatibilities without wasting a CD-recordable. Note that you may have to
eject and reinsert the CD-R after simulation before a real write can start.
Drivers
-------
The following driver IDs may be used with option '--driver':
plextor
Supports CD structure analysis (command 'read-toc') for Plextor CD-ROM
readers. Pre-gaps and index marks are detected by performing a binary
search over the Q sub-channel for each track. This method is fast and
gives very exact results on Plextor drives. The driver uses generic
SCSI commands (PLAY AUDIO and READ SUB-CHANNEL) so it may work on other
models, too, but result and speed is directly correlated to the digital
audio extraction capabilities.
plextor-scan
This is an alternate driver for CD structure analysis with Plextor
drives. It scans the Q sub-channels of a track linearly like the
'generic-mmc' driver but is faster on Plextor drives.
cdd2600
This is a native driver for the Philips CDD2000/CDD2600 drive family.
'read-toc' is implemented like in the 'plextor' driver but it is slow
and not very exact due to poor digital audio extraction capabilities of
these drives. Anyway, I don't recommend doing CD structure analysis with
the CDD2x00 because it stresses the mechanism too much.
generic-mmc
This is a driver for SCSI-3/mmc compatible CD-recorders that support
session-at-once (cue sheet based) writing. Most of the recent drives
should be compatible with this or with the 'generic-mmc-raw' driver
described below.
'read-toc' scans linearly the Q sub-channel of each track to retrieve
the pre-gap length and index marks. This method is very accurate but
takes the same time like digital audio extraction. It should also work
with recent CD-ROM readers.
generic-mmc-raw
This is an alternate driver for SCSI-3/mmc compatible CD-recorders.
It uses the raw writing interface where the driver has to provide the
PQ sub-channel data in addition to the audio data. This writing mode
allows using part of the lead-out area for audio data since the drive's
firmware has no chance to prevent this. Of course, you will get some
error message at the end of writing when the CD-R capacity is exhausted.
CD structure analysis is done like in the 'generic-mmc' driver.
ricoh-mp6200
Supports writing with the Ricoh MP6200S CD recorder. It cannot write
the Catalog Number, yet.
CD structure analysis is done like in the 'generic-mmc' driver.

Notes:
- MEMOREX CD-233E: This drive seems to ignore ISRC Codes and Catalog Number.
Pre-compiled Binaries
--------------------
The pre-compiled binaries should work with 2.0.x and 2.1.x kernels (tested
with kernel 2.0.33 and 2.1.111). Older kernels may require recompilation
because of a different maximum message size of the generic SCSI device.
Generic SCSI Device
-------------------
Cdrdao uses the generic SCSI device ('/dev/sg?') to access the CD writer.
Try 'cat /proc/devices' to check out if your kernel supports the character
device 'sg'. If not insert the corresponding module ('insmod sg.o') or
reconfigure and compile the kernel. Cdrdao opens '/dev/cdrecorder' by default
which should be a link to the appropriate generic SCSI device.
Example for copying an audio CD:
--------------------------------
1. Create a toc-file for the source CD:
cdrdao read-toc cd.toc
2. Read out the audio data to a single file (e.g. with cdda2wav):
cdda2wav -t 1 -d 4500 data.wav
3. Write the CD:
cdrdao write cd.toc
Example for composing an audio CD:
----------------------------------
Assume three existing audio files 'audio1.wav', 'audio2.wav' and 'audio3.wav'
that go in three tracks. We do not want a pause between track 1 and 2 (no
pre-gap). The first 10 seconds of 'audio1.wav' should be used as pre-gap for
track 3. Here is the toc-file:
// Track 1
TRACK AUDIO
FILE "audio1.wav" 0 // take all audio data from 'audio1.wav', length is taken
// from file
// Track 2
TRACK AUDIO
FILE "audio2.wav" 0 // take all audio data from 'audio2.wav', length is taken
// from file, no pre-gap
// Track 3
TRACK AUDIO
FILE "audio1.wav" 0 0:10:0 // take first 10 seconds from 'audio1.wav'
START // everything before this line goes into the pre-gap
FILE "audio3.wav" 0 // take all audio data from 'audio3.wav', length is taken
// from file
Type 'cdrdao show-toc example.toc' to check for the correct syntax of the
toc-file. Note that even for the command 'show-toc' the audio files must exist
if the length of the audio files is not specified like in the example.
Type 'cdrdao read-test example.toc' to check if all audio files can be read
without error (optional).
Type 'cdrdao simulate example.toc' to perform a write simulation (optional).
Type 'cdrdao write example.toc' to create the audio CD.

Notes about some CD recorder models:
------------------------------------
MEMOREX CR-622
Submitted by Bryan E. Chafy <bchafy@ccs.neu.edu>:
The drive as shipped comes with firmware that does not support DAO.
The firmware lives on a PROM, it is not flashable.
You need an EPROM burner, a 27c020 PLCC EPROM, and the
D4.0 ROM image for the CRW-1622 (can download it from Memorex web site,
the name of the image is d39e.dat).
The ROM is socketed at the rear of the drive, you will see it when you
remove the top cover. Mine had a sticker on it with the numbers E07/885B.
Note, this is for the CR-622 (and its sister the CDR-622 wearnes drive),
NOT the CRW-1622. The CRW-1622 drive is flash-upgradeable).
IMHO, Wearnes/Memorex should be sending us new ROM's free of charge because
the box clearly states the CR-622 supports DAO.
The new firmware does not turn the CR-622 into a cd-rw capable drive.
You can still only burn cd-r media.
YAMAHA CDR400, CRW4260
These drives sometimes have problems with writing at 4x speed. The
resulting disk is hard read for some reason. Disks written at 1x or
2x speed are fine. Yamaha's support is aware of this problem. It might
be related to the actual firmware revision.
I successfully wrote CD-Rs at 4x speed with a CDR400t and firmware
revision 1.0k.
