The Red Book, written by Philips and Sony in 1982, contains standards
for the original compact disc (CD). It includes the physical
characteristics of the CD and CD-DA The Red Book standard defines the
format in which an audio CD must be recorded so that it will play
correctly on a CD player. Red Book is the basis for all later CD
standards and specification documents



Any so-called CD that doesn't meet Red Book standard (e.g. Copy
Protected CDs) should not be called CDs, and you can get your money
back under the Trades Descriptions Act.

IIUC The critical point is that non-Red Book discs cannot be called *Audio*
CD's or carry the standard Logo for an Audio CD. They can, however, be
called a CD. This is because the original patents have lapsed, but Philips
still own the IPR on the logo and 'trademark' name.


I have only a couple of Copy Protected "CDs", and they have changed the
cover artwork so that it doesn't say anywhere that it is a CD, doesn't
use the CD logo, and refers to itself as a "recording" not as a CD.
Consequently what I bought wasn't a CD...it may look like a CD, it may
quack like a CD but it isn't a CD.....

This is the real problem. It is all to easy to buy a non-Audio CD by
mistake - particularly if you buy by mail order or online. This makes it
almost impossible to tell beforehand.

Slainte,
