Peter K. McGeehin 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).

  • Write element modification control using a galvanic couple
    Patent number: 8029659
    Abstract: A modification rate at a surface of an anode formed on a substrate is controlled. The anode is connected to a cathode comprised of a material having a higher nobility than the anode. An electrically conductive path is established between the anode and the cathode through an electrolyte to induce formation of an oxide layer at the anode surface that is more resistive to modification than the anode.
    Type: Grant
    Filed: July 19, 2007
    Date of Patent: October 4, 2011
    Assignee: Seagate Techology LLC
    Inventors: Peter K. McGeehin, GE Yi, Andrew B. McInroy, Brendan Lafferty
