ABSTRACT:
The present invention discloses an optical disc cartridge housing therein a magneto optical disc, wherein, a second opening for a magnetic head of the case to access is formed joining with a notch formed at an end surface of the case, and also a notch coordinating with the second opening is formed at a shutter when the shutter is at a position for opening. Thereby, it is unnecessary for the magnetic head to rise and fall in such a case where the optical disc cartridge is inserted into the optical disc driving unit, and the magnetic head accesses the magneto optical disc.
