The case comprises two circular sections comprising a bottom portion that has a readable surface and sidewalls and a top portion that has grooves that mesh with complimentary grooves in the sidewalls of the bottom portion. Holes in the top portion of the case or other gripping means are used to screw the top section into the bottom section closing the space between the Compact Disc and the case and successfully creating a protective cover capable of being played in a Compact Disc, DVD or other optical media reader. The case can be disassembled and the disc easily removed by unscrewing the case and lifting out the disc. There is also no need for a special applicator or for a special instrument to remove the disc.

[ I claim:] [1.]1. A protective optical disc case for an optical disc having a particular thickness that is able to fit into a disc player, comprising:a substantially circular top portion having threads along its circumference;a substantially circular and flat bottom portion with a sidewall along its circumference,said sidewall having an inner side with a inner diameter large enough to house the optical disc, said inner side having threads, and having an outer side with a outer diameter small enough to fit in the disc player,wherein said flat bottom portion is optically transparent to light of the frequency, and comprises a substantially rigid material;wherein the top portion when threaded into to the bottom portion defines the disc case;at least one of the top portion and the bottom portion having an aperture to allow the optical disc player rotation means to rotate the disc case;wherein the top portion when threaded into the bottom portion varies the thickness of the protective optical disc case such that the protective optical disc case conforms exactly to the particular thickness of the optical disc to compensate for variances in thickness of various optical discs such that the protective optical disc case will not substantially rotate independently of the optical disc.
