Phillip E. Gorka 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).

  • Patent number: 6563785
    Abstract: A slider that carries a transducer in a storage device having a moving storage medium, includes a leading end, a trailing end, and a top area extending from the leading end to the trailing end. The top area is designed to face substantially away from the storage medium, while a bottom area of the slider, extending from the leading end to the trailing end, is designed to substantially face toward the storage medium. The bottom area is joined to the trailing end by a curved surface having a substantially constant radius of curvature from the trailing end to a point at least 0.025 millimeters away from the trailing end.
    Type: Grant

  • Patent number: 5559429
    Abstract: A system for lapping a magnetoresistive (MR) sensor on a slider to a proper height is disclosed. The system comprises simultaneously lapping the MR lap monitor and the MR sensor positioned on the slider until a resistance of a variable resistor located within the MR lap monitor is approximately equal to a resistance of a target resistor located within the MR lap monitor. During the lapping process, a reference resistor located within the lap monitor is compared to both the variable and target resistors to prevent a lapping failure. In one preferred embodiment, the reference, target, and variable resistors are formed from a ferromagnetic metal alloy. The MR lap monitor and the MR sensor are lapped until a height of the ferromagnetic metal alloy forming the variable resistor is approximately equal to a height of the ferromagnetic metal alloy forming the target resistor.
