There are a multitude of standards...

Red book is the traditional audio standard.

Then there are yellow, orange, green, blue books and much more.

THese cover data cd's, extended audio cd's, multimedia cd's, video cd's etc etc.

Google "red book standard", and look at the Wiki.. I'm sure there will be plenty of links in there to follow into the other standards.
