  • Patent number: 6411584
    Abstract: A cartridge unloading apparatus for a disk drive having a cartridge loading end, a remote end, and a base plate. The apparatus is employed for tiltably unloading the disk from a spindle magnet with a peeling action. The apparatus includes first and second sliders positioned relative the ends of the disk drive. The sliders each have only one S-shaped slot formed therein. Each slider has a slot to receive one of the two lifting pins provided on a cartridge receiver. The movement of the sliders drives the lifting pins along the slots, thereby raising or lowering the cartridge receiver depending upon the direction of rotation of the tiller. The sliding motion of the lifting pins engaged in the S-shaped slots thus unloads a disk from or, alternatively, loads the disk onto the drive spindle.
