  • Patent number: 6424498
    Abstract: A suspension limiter for limiting travel of a read/write transducer gimbal in a disc drive is disclosed that positively engages or interlocks with a feature of the load beam supporting the gimbal, or vice versa, to preclude disengagement of the limiter during an abnormal external shock event. One embodiment has a hook on the load beam that fits within a hole gimbal to interlock the two together. Another embodiment has a hook on the gimbal that fits within a hole in the load beam during a shock event. Another embodiment has tabs on the gimbal that hook over a notch in side fingers extending from the end of the load beam on either side of the gimbal. Another embodiment has a hooked tab on the load beam that extends through an aperture in the gimbal to interlock the gimbal and load beam together during a shock load event. Each of the embodiments prevents catastrophic plastic deformation of the gimbal during such events.
