Hi!

Is there a tool to identify a CD/DVD/R/RW-manufacturer?

cat /proc/ide/hdd/model
This works if your cdrom is /dev/hdd, replace otherwise.

Cdrecord tries to detect the disk manufacturer at the beginning of the 
write process. Look for cdrecord output messages. Here is an example 
using a TDK blank CD (your messages may be different, of course):

...
ATIP info from disk:
  Indicated writing power: 5
  Is not unrestricted
  Is not erasable
  Disk sub type: Medium Type B, low Beta category (B-) (4)
  ATIP start of lead in:  -12369 (97:17/06)
  ATIP start of lead out: 359849 (79:59/74)
Disk type:    Short strategy type (Phthalocyanine or similar)
Manuf. index: 69
Manufacturer: Moser Baer India Limited
Manufacturer is guessed because of the orange forum embargo.
The orange forum likes to get money for recent information.

The only one I found so far is:

  cdrecord -dummy -v dev=/dev/cdrw /dev/null

but it does not work on non-writers, and I havent looked for such tool
too hard :-)

Example:

This shows a drive model rather media manufacturer.

this information is very.... useless...

because the information is printed into the stamper to make the blanks. And 
when a manufacturer sells its stampers to another on, or a third buys them on 
the 'second hand' or 'grey market', the ATIP information has nothing to do 
with the real manufacturer. There are even stampers, discarded by the 
dedicated vendor, because of bad quality, that are used by cheapo east asian 
manufacturers.
