  • Patent number: 5793572
    Abstract: A latch for retaining a transducer substantially in a landing zone of a storage disk of a disk drive is provided herein. The disk drive includes an actuator assembly having an actuator contact area which moves on an actuator path. The latch includes a latch arm, a latch contact area, a return device, an air vane, and a secondary stop. The latch arm rotates between an engaged position in which the latch contact area is positioned in the actuator path and a disengaged position in which the latch contact area is positioned outside the actuator path. The return member includes a ferromagnetic body which moves along a body path which is closest to a magnet of the actuator assembly when the latch arm is in the engaged position. The attraction between the ferromagnetic body and the magnet retains the latch arm in the engaged position during non-rotation of the disk. The secondary stop is spaced apart from a latch crash stop of the disk drive when the latch arm is in the engaged position.
