I claim: 1. A laser disc protection device, comprising: a fabric protective divider disc made of wet laid, water based processed, cut away, 3.0 ounce, non-woven, 85% Acrylic Latex Polyester and 15% cellulose wood pulp fabric backing material having a thickness of between 0.018 to 0.040 inches, an o
I claim: 1. A laser disc protection device, comprising: a fabric protective divider disc made of wet laid, water based processed, cut away, 3.0 ounce, non-woven, 85% Acrylic Latex Polyester and 15% cellulose wood pulp fabric backing material having a thickness of between 0.018 to 0.040 inches, an outer diameter substantially the same as an outer diameter of a laser disc to be protected, and a centrally-located aperture with a diameter substantially the same as a diameter of an aperture of the laser disc to be protected; an annular spindle adaptor ring; a spindle having a top end located higher than a top surface of the laser disc to be protected and which is permanently attached to and extends perpendicularly from the center of the annular spindle adaptor ring, and is simultaneously press fit into the aperture of the fabric protective divider disc and the aperture of the laser disc to be protected, in a close juxtaposition relationship therewith; and a round channel located in the top end of the spindle, which extends in the diameter direction of the spindle and has two ends; a detent ball made of metal or plastic press fit into each end of the round channel; and a spring made of metal or plastic located in the round channel between each of the detent balls, wherein the spring urges each detent ball to extend out of the round channel to thereby hold an inner peripheral edge of the aperture of the laser disc to be protected and allow the spindle and the annular spindle adaptor ring to releasably attach and hold the laser disc to be protected in simultaneous contact with the fabric protective divider disc and the annular spindle adaptor ring. 2. The laser disc protection device as set forth in claim 1, further comprising permanent adhesive to attach the annular spindle adaptor ring to the fabric protective divider disc.
