I think the filesystem format is just called iso 9660. I believe the writer reads the
info on the inner plastic and gets the media type since not only does it know the
difference in size but it also reads the media speed rating to know not to burn at a
higher than x speed (unless the user overrides that setting).

Is there some info pre-recorded?
