    摘要： The invention includes a yoke assembly containing a top and a bottom proximity latch magnet. The invention includes a voice coil attached to a voice coil bias steel. The crash stop includes a magnetic proximity latch created by the voice coil bias steel attracted to the top and bottom proximity latch magnets. It may also include using the magnetic proximity latch with a magnetically weakened contact latch. Experiments have shown that the combined magnetic proximity latch and the magnetically weakened contact latch require significantly less initial releasing force than the prior art crash stops, and meet rotary shock requirements. The invention includes making the actuator assembly, the voice coil motor assembly, and the CSS hard disk drive. The invention includes operating the CSS hard disk drive with at least the magnetic proximity latch.

    摘要： A latch for an actuator arm of a hard disk drive. The latch includes a damping sleeve that is molded onto a steel plate. The sleeve has a pair of collars located at opposite ends of a neck portion. The neck portion is inserted into a plastic fantail portion of an actuator arm. The steel plate becomes attached to a magnetized member of the drive when the actuator arm is rotated to an unloaded position. The attachment of the plate, latches the position of the actuator arm and prevents the disk drive heads from moving onto the data sectors of the disk. The latch is located on the longitudinal center axis of the actuator arm so that the latch does not create a twisting vibrational mode on the arm. The steel plate is located away from the voice coil magnets of the disk drive so that the latch does not create a biasing force on the arm. The latch can be assembled to the actuator arm by merely pressing the damping sleeve into an aperture of a tab that extends from the fantail of the arm.

    摘要翻译： 用于硬盘驱动器的执行器臂的闩锁。 闩锁包括模制在钢板上的阻尼套筒。 套筒具有位于颈部的相对端的一对套环。 颈部插入致动器臂的塑料挡板部分。 当致动器臂旋转到卸载位置时，钢板附接到驱动器的磁化构件。 板的附件锁定致动器臂的位置，并防止盘驱动头移动到盘的数据扇区上。 闩锁位于致动器臂的纵向中心轴线上，使得闩锁在臂上不产生扭转振动模式。 钢板远离磁盘驱动器的音圈磁铁，使得闩锁不会在臂上产生偏置力。 仅通过将阻尼套筒按压到从臂的挡板延伸的突片的孔中，将闩锁组装到致动器臂。

    摘要： A spindle motor assembly for a hard disk drive which has a fluid filled tube that dynamically balances the spindle motor. The assembly may include a hub which is rotated by an internal motor. A plurality of disks may be coupled to the hub and separated by a number of spacers. In one embodiment, the fluid filled tube is attached to the hub. In another embodiment, the fluid filled tube is attached to the spacer. The fluid within the tube is allowed to move during rotation of the hub. Movement of the fluid may dynamically balance the spindle motor.
