To look at it differently -- if you handed someone a
CDROM, and a
stack of standards describing it (ISO 9660, the Red Book, etc.) but no
computer and no CDROM drive, is that person likely to have enough
information to recover the data on the disk? I expect the answer is
"no, not even close".
I would hope that the standards give you enough information
to be able to build a CDROM drive and read back the bits
on there. I'm assuming that the stack of standards includes
information on the way the bits hang together too (the
file-system or whatever).
You ould probably not need to build the CDROM drive
for just one CD. All you need, in principle, is a
high resolution microscope and either a lot of time
or some image processing software.
What is it that you think is not properly described in
the standards?
