Abstract: A self-biasing spindle motor connector (such as 200) for a disc drive (such as 100) is disclosed. The spindle motor connector (such as 200) includes a body portion (such as 202) and a plurality of alloy contacts (such as 204) extending away from the body portion. The connector may comprise a crush rib (such as 206) extending from at least one side of the body portion and making contact with a vertical wall (such as locating edge 208) of a base plate (such as 102) of the disc drive. The crush rib ensures that the connector is properly biased to a reference edge and situated in relation to the base plate and the disc drive printed circuit board. An x-y control boss (such as 212) prevents the connector from moving in the x-y directions while the crush rib prevents the connector from rotational movement. The connector may also include a rotational boss (such as 216) that is inserted into a rotational control hole of the base plate to prevent rotational movement of the connector.

Abstract: 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.

Abstract: An apparatus and method of aligning a disc drive printed circuit board connector with a corresponding receptacle in a disc drive slot in a test fixture includes a pair of tapered guide members on opposite ends of the connector which are angled toward the pins of the connector so that the connector is centered within the receptacle as the connector is inserted into the receptacle in the test fixture. The receptacle may be mounted for lateral movement within the slot of the test fixture to move relative to the connector as the guide members slide within the receptacle to align the pins and sockets before the pins enter the sockets within the receptacle.

Abstract: A disc drive includes a locating feature for aligning an electrical connector of a printed circuit board relative to an outer dimension of the disc drive. A guide pin is formed on one of the electrical connector and a base plate of the disc drive, and the guide pin is received within an opening defined in the other of the electrical connector and the base plate to position the electrical connector relative to the base plate. In addition, a method of positioning an electrical connector of a printed circuit board includes the step of inserting a guide pin formed on one of the electrical connector and the base plate into an opening formed in the other of the electrical connector and the base plate to align the electrical connector with the base plate. The method further includes the step of fastening the printed circuit board to the base plate of the disc drive while the guide pin remains within the opening.

Abstract: 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.
