Optical disc cartridge.

摘要

An optical disc cartridge housing a magneto optical disc, comprising an opening (5) in the case (1) for access of a magnetic head which joins with a notch (15b) at an end surface of the case. A notch (17) coordinating with the opening (5) is formed at a shutter (2) when the shutter is at a position for opening. Thereby, it is unnecessary for the magnetic head (10) to rise and fall when the optical disc cartridge is inserted into the optical disc driving unit, and the magnetic head (10) accesses the magneto optical disc.
