Abstract
A magneto-optic disk unit includes a cartridge holder having an insertion opening, an inside surface and first and second surfaces, an erroneous insertion preventing mechanism having at one end a stopper portion for prohibiting erroneous insertion of a magnetic disk cartridge and at the other end an insertion detecting portion for detecting insertion of a magnetic-optic disk cartridge, and a supporting mechanism for rotatably supporting the erroneous insertion preventing mechanism. The insertion detecting portion projects inside of the cartridge holder from an upper surface of the cartridge holder, so that when the magneto-optic disk cartridge is inserted the insertion detecting portion moves outside of the cartridge holder to allow insertion of the magneto-optic disk cartridge, and that when the magnetic disk cartridge is inserted the insertion detecting portion does not substantially move, thus permitting the stopper portion to prevent insertion of the magnetic disk cartridge.
