This looks a much better proposition. The problem with the two types
I was describing is the disc is held tight on the centre boss. To get
the disc off, most users will naturally lever up one edge (which puts
the play side of the disc in contact with the case material) and then
rotate it as they pull it off the boss - thus introducing scratches
without even trying.
