  • Publication number: 20070002494
    Abstract: In a dynamic electric test, a head slider is to be fixed positively to a suspension and to be removable easily from the suspension in accordance with the result of the test. In one embodiment of the present invention a head gimbal assembly includes a head slider, a gimbal and a load beam. The head slider is disposed on a gimbal tongue and is held with an urging force of a resilient clamp at a position between the resilient clamp formed on the leading side of the head slider and connecting terminals formed on the opposite side thereof.

  • Publication number: 20060285252
    Abstract: A head assembly for a data storage device. The head assembly has a suspension. The head assembly also includes a contact pad coupled to the suspension, such that the contact pad does not overlap the stainless steel edge of the suspension, thereby allowing greater flexibility for the contact pad. The head assembly also includes a slider. The slider is coupled to the suspension at the slider mounting point. The slider mounting point is at least partially bounded by polyimide standoffs. The polyimide standoffs are positioned and sized to provide an adhesive pocket with an increased area, and the polyimide standoff closest to the contact pad is positioned to reduce the effect of the solder shrinkage moment.

  • Patent number: 7009816
    Abstract: To strengthen a flying lead portion of a long-tail flexible printed circuit (FPC) integrally formed with a flexure, stacked support portions of resin layers on both sides of a flying lead 7 of a long-tail FPC 6 are reinforced with metal frames 14. A fold-back portion 9 of the long-tail FPC 6 is folded back at 90 degrees so that flying lead 7 is disposed parallel with a turning shaft 21 of a carriage 20. The flying lead is then joined to a connection pad 26 on a main FPC board 24 using solder 18.

  • Publication number: 20060034017
    Abstract: Embodiments of the invention limit a pitch attitude angle of a magnetic head slider during loading without allowing gimbal stiffness of a flexure in an ordinary flying state to be increased. In one embodiment, a limiter formed by part of a flexure is disposed so as to provide a clearance from a lift tab formed by part of a load beam. A limiter clearance, if the clearance between the limiter and the lift tab is so called for convenience sake, must be maintained as a physical clearance when a magnetic head slider is in an ordinary flying state. The lift tab and the limiter are disposed on a side of an air inflow end of the magnetic head slider. The limiter clearance during unloading is thereby made small so as to allow proper and positive unloading operation.

  • Publication number: 20050190503
    Abstract: Due to the raised operating rotation speed, it has become an important technical theme to reduce fluid vibrations caused by high speed air flows passing the wiring extension in a head gimbal assembly in order to raise the positioning accuracy for higher density recording. Embodiments of the present invention provide a spring structure to the wiring extension. In a wiring extension holding section formed on the carriage side, the wiring extension is retained at the center of the groove of the holding section by the repulsive force of spring members. By preventing the wiring extension from being directly subject to high speed air flows generated by a high-speed rotating disk, this structure is intended to suppress vibrations of the wiring extension caused by high-speed air flows passing the wiring extension.
