-8- ABSTRACT: "Optical disc cartridge." An optical disc cartridge is provided which offers protection to the radiation-sensitive recording layer from damage due to mishandling while at the same time allowing a high recording density. The radiation-sensitive layer is applied to a rotatably supported disc-shaped member which is completely surrounded by a sealed enclosure. An access window is then formed in the enclosure through which a laser beam may be focused for the recording and reading of information on the radiation sensitive layer. A magnetic drive may be used for rotating the disc-shaped member.
