    Abstract: Described is a preamp flex cable for use in a hard drive. The flex cable incorporates a stiffener layer operable to provide a mechanical support, an insulating layer provided over the stiffener layer and having at least one via provided therein to expose the stiffener layer, and at least one conductive layer provided over the insulating layer. The at least one conductive layer forms an electrical circuit and at least one heat removing element that extends through the via and establishes a contact with the stiffener layer. In one implementation, the heat removing element includes a rectangular plate having a recessed center portion and an edge portion. The recessed center portion protrudes through the at least one via in the insulating layer to mechanically couple with the stiffener. In another implementation, the heat removing element includes first portion and second rectangular portions. The first portion protrudes through the at least one via in the insulating layer to thermally couple with the stiffener and the second portion is disposed over the insulating layer, such that the second portion can be thermally coupled to the preamp.

    Abstract: A method (and apparatus) for operating a disk drive apparatus. The method includes moving a movable member about a fixed position to move a read/write head coupled to a slider to a selected track on a disk. The selected track is at least one of a plurality of tracks. The method includes adjusting a position of the read/write head using an actuating device integrated on the gimbal. The actuating step moves the read/write head relative in a manner normal to the track on the magnetic disk to align the read/write head on the track using a finer and faster alignment of the read/write head than the moveable support member.

    Abstract: Apparatus and techniques for measuring dimple-gimbal separation force for a suspension assembly in a computer disk, commonly called a hard disk drive (HDD), for understanding the impact on suspension dynamic performance. More particularly, the present invention provides readily procedures and methods for measuring the contact force exert between a gimbal and dimple of a HDD suspension assembly. Merely by way of example, the present invention is implemented using such procedures and methods to directly probe the gimbal-dimple contact force, yet it would be recognized that the invention has a much broader range of applicability on any mechanical apparatus that is small in dimension and structure stiffness, such as, micro actuators and micro electrical and mechanical system (MEMS) devices.
