Abstract: A protective disk case comprises a thin box having a rigid top shell and a rigid bottom shell which cooperatively fit together to define an enclosed area which is sized to receive a recording disk. The top and bottom shells are separatable so that the front and back side of the disk case are separatable into two parts. Furthermore, there is included a locking means and a hinge means for connecting and locking the top and bottom shells together. One embodiment describes a circular bevelled edge within the enclosed area for supporting the recording disk without having the sides of the disk contacting the inside of the protective disk case. A hook may be attached to the top of the protective disk case to allow hanging of the case from a support rod. Furthermore, there is disclosed a second, thin box having an open side to allow for insertion of the protective disk case to facilitate in the storage and handling of individual recording disks.
