Well, sort of. I might have the nomenclature slightly off. Audio CDs are
written using "Red Book" format. This can be thought of as a sort of
primitive file system, as it does contain certain metadata about what's on
the CD. I think it would be feasible to produce an "audiofs" interface,
but perhaps it's so simplistic that it's unnecessary to do so. The tracks
themselves are raw data, AFAIK (i.e. there isn't any header info in the
track itself). But, info about # of tracks, run time, disk serial number,
etc., are stored somewhere. Otherwise programs like GCD and cdparanoia
would have to scan the entire CD before being able to jump to track, etc.
