  • Patent number: 6356410
    Abstract: A head structure for writing data on a magnetic media including a first pole having an upper surface and a write gap covering a portion of the upper surface. An upper pole tip formed on the write gap having a first width. A second pole having a second width greater than the first width and coupling to an upper surface of the upper pole tip. A conductive coil magnetically coupled to the first pole and the second pole to induce magnetic flux within the first and second pole in response to a current flowing in the coil.
    Type: Grant
    Filed: June 12, 2000
    Date of Patent: March 12, 2002

  • Patent number: 5745983
    Abstract: A tool for batch processing the definition of air bearing surfaces on rows comprising a plurality of sliders is disclosed. The tool has a main body member having a length defining a y-axis direction, a width defining an x-axis direction, and a thickness defining a z-axis direction. The main body member has a top surface defining an upwardly facing z-axis base surface. The main body also defines a y-axis alignment reference surface, and an x-axis alignment reference surface. The rows are positioned on the tool for processing, where the upper surface of the platform engages the lower surface of the plurality of rows to provide proper z-axis positioning on the tool. The y-axis alignment reference engages one longitudinal side of an anchor row to provide proper y-axis positioning, and the x-axis alignment reference surface abuts the second end of the plurality of rows to provide proper x-axis positioning. The top surfaces of the rows lie in a common plane.
