Correct, but data CD's have another layer of error detection, which further reduces the data capacity by another 15%. Audio CD's have 2352 databytes per sector, while CDROMs have 2048. The section on Data Structure on Wiki covers this in detail: http://en.wikipedia.org/wiki/CD#Storage_capacity_and_playing_time As Opaqueice says, poorly made disc's are not an overwhelming problem, I encounter fewer than he does, but they do exist. Also the problems appear to be poor metalization or pressing, so have a much larger defect area's than a 2.5 mm scratch. Tools like EAC and AccurateRip allow me to verify that I've got bit perfect rips.
