Abstract: The disk case herein includes a narrow rectangular housing having an interior volume defined by two flat, closely spaced and parallel opposed rectangular surfaces joined aroung the four common edges thereof by a narrow perimeter edge extending there between. A disk access slot extends through one of the perimeter edges along substantially the length thereof and communicates with an interior disk retaining space. A disk receiving track extends along the perimeter of the disk retaining space. A portion of the track extends along an inclined plane which plane extends downwardly in a direction from the back perimeter edge to the front perimeter edge. A disk release mechanism is partially cut out from or formed from one of the rectangular sides, the exterior surface thereof being substantially flush with the exterior surface of the rectangular side, and located adjacent the top perimeter edge and positioned substantially along the middle thereof.
