Hi I wonder if someone can give me (or point to) a simple explanation
as to the difference between data CD and audio CD formats.


An audio CD is a linear array of samples @ 44.1khz, 2 channels, 2 bytes
per sample. There's a table of contents at the start and a disk ID.
That's about it.


Not quite. The audio stream is encoded with some redundancy for error
protection, and combined with streams of information regarding the track,
time from start, etc.

A data CD has a file system and extra error correction wrapped around
the data blocks.


Slainte,
