  • Automated and accurate high-throughput slider-level flatness inspection
    Patent number: 10281268
    Abstract: A method includes receiving an image of a surface of a slider bar from an interferometer, where the slider bar includes at least two sliders, and where the image includes image data according to at least two image data channels for a slider bar surface and the at least two sliders. The method also includes generating a slider bar map of the surface of the slider bar based upon the image data of the image, where the slider bar map includes at least two data channels and ascertaining a plurality of individual slider surface maps based on a number of sliders included on the slider bar, where the ascertaining is also based upon the slider bar map having the at least two data channels. The method also includes segmenting the slider bar map according to the plurality of individual slider surface maps.

  • Method and apparatus for coupling a laser diode to a magnetic writer
    Patent number: 8873348
    Abstract: A write head includes a cavity configured to couple a laser diode to the write head. A bottom of the cavity includes a heat conductive element configured to contact the laser diode, a plurality of thermal studs disposed below the heat conductive element, and a substrate disposed below the thermal studs. The heat conductive element, thermal studs, and substrate are thermally coupled to draw heat from the laser diode.
