  • Method and apparatus for processing sliders for use in disk drives and the like
    Patent number: 6916227
    Abstract: A system and method are described for processing a slider (e.g., one to be used in a disk drive apparatus). Corners of the sliders are abraded while still a part of a row of sliders in a part-off operation. By abrading the corners of the sliders, head slap events between the slider and the recording media result in less damage to the recording media and less particulate matter from the slider being left on the recording media, improving data integrity for the recording media.
    Type: Grant

    Date of Patent: July 12, 2005
    Assignee: SAE Magnetics (H.K.) Ltd.
    Inventors: Niraj Mahadev, Manuel A. Hernandez

  • Method and apparatus to provide a GMR lapping plate texturization using a photo-chemical process
    Publication number: 20040077294
    Abstract: A system and method are described for manufacturing a lapping plate. In one example, the lapping plate is made by covering a Tin-Antimony plate with photoresist and exposing the resulting photoresist layer with UV light through a wire mesh mask. After development, the non-etch areas can serve as land areas for diamond charging. Such a method may lead to fewer artifacts on the lapping plate and smaller diamond particle dimensions resulting in better processing of read/write heads, especially GMR heads.
