  • Publication number: 20060232271
    Abstract: A dynamic electrical tester (DET) for testing head gimbal assemblies (HGA) is disclosed. The DET simulates disk drive operation while significantly reducing tester capital investment. Multiple HGAs are tested simultaneously using modular spin stands with shared electronics. This design increases utilization of electronics and minimizes the effect of spindle start/stop time. A parallel array of spin stands with shared electronics is used to reduce tester component and materials cost by multiplexing between the spin stands. The DET has the significant advantage of reducing wait time by making use of the electronics while they are idle during mechanical-related delays. In addition, the DET includes more channels per test head that can readily switch back and forth between the products being tested.

  • Patent number: 7035047
    Abstract: A magnetic head having read and write elements is provided according to one embodiment. The head includes a substrate. An undercoating is coupled to the substrate. The undercoating has a preferred thickness of between about 1.5 and 0.5 microns or less in a direction perpendicular to the planar surface of the substrate engaging the undercoating. Preferably, the undercoating is reduced to a desired thickness during fabrication using chemical mechanical polishing. The undercoating is constructed of a material having a thermal conductivity greater than that of amorphous Al2O3. An electric contact pad is operatively coupled to a layer positioned between the pad and the undercoating. Electric contact pads of read and write elements are preferably separated from the undercoating by insulation planarization layers. A write element is coupled to the undercoating. The write element has an electrically conductive coil.
