That's pretty much it as far as common use goes however dictionary.com states the 2 as being interchangeable, Disc deriving from the original Disk, the former apparently being the preferred English version, the latter being the preferred American English.Pielikey said:I always figured it was disc if you're talking about the circly plastic things you put in computers and game consoles and DVD players.
Disk only refers to the floppy kind as far as I know.
