I've never quite been convinced of this. Where I have the problem is
that data CD's work day-in and day-out making perfect copies of the
bits, but for an audio CD this somehow stops working?
I understand that when played in a "normal" CD player, things go along
in real time and the player just does the best it can reading the disk.
If there are errors, it does some basic correction, but mostly just
guesses or skips the bit. CD-ROM drives in computers aren't very good
at that -which I thought was what some of the CD anti-copy schemes rely
on.
If you want an "exact" copy, can't you just put the CD in, grab the
aiff files that show up in the Finder and drag them over. AFAIK, as
with any Finder copy, if even one bit can't be read, you'll get an
error.
I'm still struggling with why that wouldn't work in practice.
