Magnetic disk cartridge

摘要

In a magnetic disk cartridge, a guide member is positioned on a lower half of the cartridge. The guide member has a guide surface standing face to face with a part of a guide groove extending in the surface of the lower half. The guide surface restrains upward movement of a link member coupled with shutter members for magnetic head insertion apertures of the cartridge after the lower side edge portion of the link member is fitted to the guide groove of the lower half when the cartridge is assembled. To prevent the aperture opening movement of the link member, a lock member or a stop wall portion is positioned at a side wall portion of the cartridge.
