One successful metric for "what is compression" is this:
Any method by which a smaller volume that *can be
deterministically expanded to the original with no extra information*
can be considered compression.
This of course, leads to discussions about lossy vs lossless
compression. Is the original the exact string of bits, as in a
gzipped text file or binary, or is it the experience of the original,
as in a vorbis file made from a CD?
I would say that, since one could take a linear-encoded
laserdisc and turn it to an angular-encoded disc, that this can be
considered a form of compression. It's necessarily going to be lossy,
though, since you lose 2/3 of the outer ring's resolution (preserving
the overall experience of the information).
