RE: [linux-audio-user] Strict Red Book - Linux-audio-user

9 Dec 2004

   I'm trying
to burn some audio CD's and I always run
 into the problem that there are some CD players that
 just don't want to play the CDs that come out of my
 burner. I'm burning them in raw on a Plextor drive,
 so it _shouldn't_ be having problems. 
I trying to think of ways that the hardware could have
an impact and am failing to think of anything. Does
that make any sense? 
Some of the cheaper burners have bugs in the firmware that result in crappy CDs. Some
don't support various modes of burning CDs. Plextor has a good reputation for features
and quality drives.

...
   Apparently
the
 CD's are not strictly compliant with Red Book specs
 though. (from the documentation CDrecord uses CD-DA
 rather than Red Book, I'm not quite sure what the
 differences are) 
If CD-DA isn't Red Book, then I wonder what is. My
impression has been that Red Book is simply the method
by which the audio files are burned onto the disk.
There are two methods; A, Disk at Once (DAO) and B,
Track at Once (TAO). Red Book is DOA. 
...
 From cdrecord's man page: 
"-audio If this flag is present, all subsequent tracks are written in CD-DA (similar
to Red Book) audio format."

I would take that to imply that there are some differences.

You can also write in RAW mode, which tends to be more accurate than DAO mode.  When I use
DAO mode the subchannel data is offset by 2 seconds. I usually burn audio CDs in RAW96r
mode. More from the cdrecord man file:

"-raw96r Select Set RAW writing mode with 2352 byte sectors plus 96 bytes of raw  P-W
 subchannel data resulting in a sector size of 2448 bytes. This is the preferred raw
writing mode as  it  gives  best  control over  the  CD  writing  process.  If you find
any problems with the layout of a disk or with sub channel content (e.g. wrong  times  on
the  display  when playing the CD) and your drive supports to write in -raw96r or -raw16
mode, you should give it a try. There are several CD writers with bad firmware that result
in broken disks when writing in TAO or SAO mode."

...
   This is quite
annoying when I give people a CD and
 it turns out their palyer can't handle it. (Once
 there was even a CD-ROM drive that wouldn't play
 it!) Does anybody know of any solutions for this? 
I just use my own scripts to burn CDs. I've never had
a problem. What program do you use to write the CD?
And if you post a TOC file maybe someone here can spot
something wrong with it. 
I generally use cdrecord directly or use GCD Master.

...
 Nobody else responsed which is why I am. Not because I
really know much about it. Although, I never have
problems with the CDs that I burn. 
I personally never have problems with them either, but there are some cheap boom boxes out
there have a real problem seeking tracks on my CDs.
