Patents by Inventor Frank Richard Reynen

Frank Richard Reynen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus for the application of an advanced texture process
    Patent number: 6277005
    Abstract: Apparatus for removing random scratches formed during the polishing of magnetic recording media, and for disposing on the surface of the media a near-circumferential texture which increases the recording reliability of the media while simultaneously reducing its failure rate. The present invention teaches the application of a low unit load force to a pad and polishing tape combination in contact with a rotating and oscillating disk surface to completely remove the random scratches previously formed by a polishing step. The apparatus facilitates the application of a specially designed, extremely fine alumina slurry composition without producing similar size circumferential scratches at the high surface speeds.
    Type: Grant

  • Advanced mechanical texture process for high density magnetic recording media
    Patent number: 6129612
    Abstract: Method for removing random scratches formed during the polishing of magnetic recording media, and for disposing on the surface of the media a near-circumferential texture which increases the recording reliability of the media while simultaneously reducing its failure rate. The present invention teaches the application of a low unit load force to a large surface pad and polishing tape combination while in contact with a rotating disk surface that is also moving in a circumferential direction to completely remove the random scratches previously formed by a polishing step. The scratches are removed with the aid of a specially designed, extremely fine alumina slurry composition which prevent producing similar size circumferential scratches at the high surface speeds. The methodology provides for a smoother disk surface than prior known super-polish/texture methodologies.
