Tips for MMC RAW mode writing.
|
||
|
|
|
||
|
|
This allows to do disk at once recording on Philips drives that
|
||
|
|
do not support SAO.
|
||
|
|
|
||
|
|
You may write audio tracks in RAW mode. There are some new
|
||
|
|
and most likely transient options:
|
||
|
|
|
||
|
|
-raw16 Write 2352 Bytes sectors + P+Q Subchannel
|
||
|
|
|
||
|
|
-raw96r Write 2352 Bytes sectors + P+W Subchannel (R-W in raw mode)
|
||
|
|
|
||
|
|
-raw96p Write 2352 Bytes sectors + P+W Subchannel (R-W in packed mode)
|
||
|
|
|
||
|
|
NOTE that the MMC standard does not allow -dummy in RAW mode.
|
||
|
|
There may be drives which allow it but don't bother if it does not work.
|
||
|
|
|
||
|
|
Indices are fully supported in RAW mode.
|
||
|
|
|
||
|
|
MCN & ISRC are not yet supported in RAW mode, they are silently discarded.
|
||
|
|
|
||
|
|
If you find other problems in RAW mode or if you find
|
||
|
|
new bugs introduced in old write modes, please send a bug report.
|
||
|
|
|
||
|
|
Cdrecord now checks the properties of the writer. If a specific write
|
||
|
|
mode is not supported by the writer, cdrecord warns you and makes
|
||
|
|
a suggestion for a similar alternate write mode.
|
||
|
|
|
||
|
|
With the curent structure of cdrecord, it is not possible to silently
|
||
|
|
e.g. change the write mode from -dao to -raw96r
|
||
|
|
|
||
|
|
MMC compliant drives are automatically scanned for supported write modes.
|
||
|
|
This should help to make cdrecord work without manual static configuration.
|
||
|
|
My hope is still to have no need to know all drive properties in
|
||
|
|
advance, so new drives will continue to work as long as they
|
||
|
|
are standard compliant enough for cdrecord.
|
||
|
|
|
||
|
|
EXAMPLES:
|
||
|
|
|
||
|
|
cdrecord dev=1,0 -v -raw96r *.wav
|
||
|
|
|
||
|
|
will write a audio CD in raw mode using (computed) 2448 byte sectors
|
||
|
|
with raw P-W subchannels. This works e.g. with Plextor drives.
|
||
|
|
|
||
|
|
|
||
|
|
cdrecord dev=1,0 -v -raw16 *.wav
|
||
|
|
|
||
|
|
will write a audio CD in raw mode using (computed) 2368 byte sectors
|
||
|
|
with raw P+Q subchannels. This works e.g. with Philips drives.
|
||
|
|
|
||
|
|
|
||
|
|
NOTE: The input sector size always is 2352 bytes for audio.
|
||
|
|
|
||
|
|
IMPORTANT:
|
||
|
|
|
||
|
|
- if the drive supports RAW/R96R among with other raw write modes,
|
||
|
|
use -raw96r
|
||
|
|
|
||
|
|
- if the drive does _only_ supports RAW/R16, use -raw16
|
||
|
|
|
||
|
|
- ... else if the drive supports RAW/R96P, use -raw96p
|
||
|
|
|
||
|
|
The packed raw mode (RAW/R96P) is buggy in Plextor drives and
|
||
|
|
the RAW/R16 mode is buggy in TEAC drives. Plextor creates
|
||
|
|
unreadable disks and TEAC hangs the drive.
|
||
|
|
|
||
|
|
For this reason, it is important to select the raw writing
|
||
|
|
mode accoding to the notes above.
