     Hmmm, well, this is not an audio disc.  :)

Well, it could be!  There's a song by Aphex Twin which was supposedly
made from an image of the artist's face.  Supposedly, you can take the
track's raw audio, lay it out in a certain way, and get the picture
back.  (This song is generally referred to as "strange formula"
because its name is reportedly a bunch of symbols which nobody
understands and I've never seen.)
