摘要： A coil construction for a voice coil motor is disclosed. The coil construction includes a series of stacked planar coils disposed on a substrate material. Each planar coil is separated from its neighboring coil or coils by a viscoelastic material to reduce vibration of the coil construction. The coil construction is attached to an actuator arm. Control circuitry creates a current in the coil construction to position a head on the actuator arm. Also disclosed is a method for making a coil for a voice coil motor. The method includes the steps of masking a substrate having a conductive layer with a photoresist, exposing the mask to create a pattern of planar coils, developing the photoresist, and etching the conductive layer to create a planar coil.

摘要： 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.

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.
摘要翻译：一种用于在机械冲击事件期间减小驱动器组件在盘驱动器内的头盘组件内的偏转的装置和方法。缓冲器被固定到头盘组件的固定部分，并且具有缓冲体和连接到缓冲体的两个或更多个缓冲臂。相邻的缓冲臂在它们之间形成槽。致动器组件的一部分可以插入每个槽中，由此缓冲臂将在机械冲击事件期间减小致动器组件的偏转运动。
