There is error correction built into the mechanism of reading > data from the physical medium of a CD. well, if i said i'm not an expert on the physical layer of cds, that would be and understatement, the truth is that i hardly know a word about that. but i think you're right, it seems to me that some of what has been said on this thread assume a rather simplified model of how the data is written and read in an audio cd. haven't reread my pohlman lately (that means many years), but i remember it was a good reading. there may be many better resources now, but pohlman was highly recommendable on the subject. best, lj
