Red Book CD Audio still has error correction. Otherwise you'd *really* 
notice the scratches.

Otherwise, yes, as Dan said, The technology is almost 30 years old, and 
it's designed much more like a digital phonograph than a computer 
storage disk. CD-DA isn't even block addressable in the normal sense. 
The data is written in a continuous spiral from start to finish, with
local signposts to help seeking.

At the time, I expect there was no expectation of using it for data 
storage, and no need for the overhead of a conventional filesystem.

Even DVD-Video only provides the filesystem structure as a convenience. 
IIRC it's possible to play a dvd by accessing the ifo files at a fixed 
offset and using the embedded sector references.
