>Isn't reading digital audio data done the same?
No it isn't. CD players have real-time error correction. If the
error-correction fails then it may have silence or it may try to reread. If
it has trouble tracking then you'll get skips.
By the way, CD Roms have more error-correction codes than Red-Book audio
does (and therefore less data density), and CD burners tend to have CD Rom
error-correction in hardware, while cheap readers rely on software
error-correction and handle errors much more slowly.
