    摘要： 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.

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.

    摘要： A wired circuit board has an insulating layer extending in a longitudinal direction, a conductive layer having a plurality of signal wirings covered with the insulating layer and arranged in mutually spaced-apart and parallel relation in a perpendicular direction to the longitudinal direction and a thickness direction of the insulating layer, and connecting terminals provided on both longitudinal ends of each of the signal wirings and exposed from the insulating layer, and a ground layer covered with the insulating layer and formed to surround each of the signal wirings in a perpendicular direction to the longitudinal direction. A slit along the longitudinal direction is formed between each of the signal wirings in the insulating layer.

    摘要： Systems and methods for flexure based shock and vibration sensor for head suspensions in hard disk drives. Specifically, this invention deals with operational shock and vibration management within a hard disk drive. In one implementation, the assembly includes a circuit embedded optical waveguide sensor that includes a flexible electrical circuit board with a configuration of either a single or multi layers of conductor traces, a thin flexure gimbal for carrying and flying a HDD slider, a consecutive sensing layer constructed by an optical core and by clad construction with a configuration of either a single core array or a plural core array, an optical loop formed by light input and an output core, optical grating disposed on the consecutive sensing layer forming an optical grating waveguide sensor, a light emitter for injecting light into the optical core, and a receiver receiving the output light from the optical core.
