Difference between data CD and audio CD formats

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.

A friend of mine was trying to produce an audio CD and (I think) produced a
data CD. They thought it is all data, so formats must be the same.
I want much technical detail, just something clear (and authorative) enough
to indicate there is a difference.
As an aside, another friend of mine tried to put a data CD with midi files
into his CD player - oh, it's just music :-)

Cheers

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.

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

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.

the data blocks.

Slainte,

Different file systems. A computer will read either, (with suitable
software). An audio CD player wants to see an "audio" cd.

All he really needs to know is that his CD burning program offers to
burn both types. Choose the right one :-)

EFM.

And Andrew, it's "delete"!
