George V. Kelley 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).

  • Thin film write head having a laminated, flat top pole with bottom shaper and method of fabrication
    Patent number: 6975486
    Abstract: A writer for high frequency, data storage heads. The writer includes a first magnetic pole upon which a write gap pedestal is formed with an upper pedestal layer of high moment material with a planar upper surface. An electrical coil is formed on the first magnetic pole. A write gap layer is deposited on the upper surface of the upper pedestal layer. The writer includes a second magnetic pole disposed above the first magnetic pole with a magnetic, flat, top pole layer. The second magnetic pole includes a bottom shaper fabricated from high moment material positioned between the coil and the top pole layer. An insulation insert separates the bottom shaper from the upper pedestal layer. The second magnetic pole includes a thin dielectric lamination layer that separates the top pole layer from the bottom shaper to disrupt the path of eddy current in the second magnetic pole.
