摘要： A method to assemble a disk drive having a spindle that includes a hub. At least one disk is placed on the hub. A clamp is fastened to the hub by a plurality of threaded fasteners. Each of the plurality of threaded fasteners is initially tightened. After initial tightening, an initial couple imbalance of the spindle is determined. After the initial couple imbalance is determined, a first selected threaded fastener of the plurality of threaded fasteners is selected and rotated by a first amount of rotation that is significantly different from a second amount of rotation of a second selected threaded fastener of the plurality of threaded fasteners. The selection and rotation of the first selected threaded fastener of the plurality of fasteners is determined based on the initial couple imbalance of the spindle.

摘要： There is provided a disk drive that includes a base, a limiting member, an actuator, and a latch. The actuator includes an actuator catch with a catch path. The latch contacts the limiting member with the latch in an open position. The latch is biased to rotate to a defeat position. An arresting portion is in the catch path with the latch in a closed position. The arresting portion is not in the catch path with the latch in the open position, and not in the catch path with the latch in the defeat position. A crash stop portion contacts the actuator with the latch in the closed position and with the actuator in a stop position. The crash stop portion does not contact the actuator with the latch in the defeat position. Also provided is a method of reworking a disk drive having the latch.

摘要： 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.

摘要： A fastener comprises a shaft extending along a longitudinal axis, and a sleeve wrapped partially around the shaft. The sleeve comprises an inner surface adjacent the shaft, an outer surface, an upper extent, a lower extent, a first circumferential extent, a second circumferential extent, and a gap extending longitudinally from the upper extent to the lower extent and separating the first circumferential extent from the second circumferential extent. The sleeve has a first thickness adjacent the first circumferential extent that is less than a second thickness between the second circumferential extent and the first circumferential extent. A cross-sectional centroid of the shaft between the upper extent and the lower extent is in substantially the same location, with the sleeve in different first and second rotational positions.

摘要： A fastener that includes a shaft and a sleeve is provided. The shaft extends along a longitudinal axis that passes through a central portion, e.g., the centroid of a head of the shaft. The sleeve is wrapped partially around the shaft. The sleeve has a gap that separates first and second circumferential extents thereof, a first thickness adjacent the first circumferential extent, and a second thickness between the second circumferential extent and the first circumferential extent. The first thickness is less than the second thickness. The sleeve has a first rotational position relative to the shaft and a second rotational position relative to the shaft different form the first rotational position. The longitudinal axis is in substantially the same location in both the first and second rotational positions.
