The so-called cdr data is in fact raw PCM data without any headers at all. It 
is the data portion of both cda files (cd audio tracks) and wav files.

wav files and cda files are both RIFF files. cda files are not as versatile as 
wav (it's locked at 44.1 kHz for instance), so wav files have more meta data 
information to describe the PCM data.

The difference between burning .wav and .cdr (or .cda) is the difference 
between being able to play the music in a standard cd player and not. Simply 
put, an audio cd that is to be used outside a computer needs to be in cda 
format.

A more technical description can be found on a number of places on the net.

has a good description of the wav format.
