Abstract
A disk drive includes an actuator rotatably coupled to a disk drive base. A fixed member is in fixed spatial relation to the base. A latch is rotatably coupled to the base. The latch includes a catch portion in contact with the actuator with the latch closed and not in contact the actuator with the latch open. The catch portion comprises a first material. The latch includes a crash stop portion comprising a second material having a lesser stiffness than the first material. The crash stop portion includes a stop portion and a pusher portion. The stop portion is in contact with the fixed member with the latch closed and not in contact with the fixed member with the latch open. The pusher portion is in contact with the actuator with the latch closed and with the actuator in an extreme rotational position.
