摘要： An apparatus and method for reducing deflection of an actuator assembly within a head disc assembly in a disc drive during a mechanical shock event. A snubber is fastened to a stationary portion of the head disc assembly and has a snubber body and two or more snubber arms connected to the snubber body. The adjacent snubber arms form slots therebetween. A portion of the actuator assembly may be inserted into each of the slots whereby the snubber arms will reduce the deflective movement of the actuator assembly during a mechanical shock event.

摘要： A data handling system having a voice coil motor having a first magnetically permeable plate and a second magnetically permeable plate is disclosed. The first magnetically permeable plate is coupled to a permanent magnet pair and the second magnetically permeable plate includes a raised plate portion directly opposite the permanent magnet pair. Planar surfaces of the permanent magnet pair and the raised plate portion are substantially parallel to each other and are spaced by an air gap. A voice coil is positioned in the air gap and moves in response to a magnetic interaction between a magnetic field produced by a controlled current through the coil and a magnetic field between the permanent magnet pair and the raised plate portion. The planar surfaces of the permanent magnet pair and the raised plate portion may be substantially identical in shape and surface area.

摘要： An inertial latch apparatus for maintaining an actuator arm in a disc drive in a predetermined position has an elongated inertial beam member pivotally mounted in the disc drive for rotation in a plane parallel to the plane of rotation of the actuator arm and a latch member pivotally mounted in the disc drive for rotation between a disengaged position permitting movement of the actuator arm when the latch member is in the disengaged position and an engaged position in interference relation to a portion of the actuator arm to prevent movement of the actuator arm when the drive is subjected to an external shock load. The latch member rotates in only one direction in response to rotation of the beam member in either a clockwise or counterclockwise direction from a neutral position.
