ABSTRACT:
A disk cartridge and a disk cartridge drive mechanism are disclosed. The disk cartridge includes a flexible recording disk with a hub at the central portion thereof, and a cartridge case containing the recording disk, with the hub having formed therein a chucking hole and a positioning hole. In order to rotate the recording disk by loading it into the disk cartridge drive mechanism, the chucking hole is defined by two straight-line portions that intersect to form a corner against which a spindle shaft of the disk cartridge mechanism is capable of being pushed, and the positioning hole is defined by a contact portion with which a drive pin of the disk cartridge drive mechanism is capable of coming into contact only in the direction of rotation of the recording disk.
