CD-DA (Audio CD) is indeed a pile of bits, but has at least two problems making a simple block-device-style copy a complicated affair: no precise positioning (seek) information, and relatively weak error correction.

Here's another answer from someone who understands the details better than I:

thought a CD just a pile of bits like a regular hard disk.
