  • Patent number: 4310864
    Abstract: An improvement to allow easier detaching of a disk memory module from its magnetic attachment to the spindle of a front loading disk drive. In one such type of drive, manually pulling a door open actuates a track-mounted carrier which lifts the disk module from the spindle, breaking the magnetic attraction between them, and transporting the module to the open door for manual removal. To reduce the force necessary to break the magnetic attraction, this invention employs an actuator fixed to the carrier which engages a crank mechanism when the carrier is being pulled to the opening. The crank mechanism pushes against the underside of the module and assists its breaking loose from the spindle. A spring holds the crank assembly in position to re-engage the actuator when the carrier is in the module-detached position.
