  • Media certification device design
    Patent number: 8297113
    Abstract: A glide head with a slider body that has a leading edge, a trailing edge and an air bearing surface is disclosed. The glide head also has an array of thermal proximity sensing elements connected in a bridge circuit that are adjacent both the trailing edge and the air bearing surface, a heating element mounted to the glide body for elevating the temperature of the thermal proximity sensing elements in relation to the temperature of an inspected surface, and a controller coupled to the array of thermal proximity sensing elements. The controller receives signals from the thermal proximity sensing elements, and determines the existence of a surface variation in the inspected surface based upon differences in the signals received from the thermal proximity sensing elements.
    Type: Grant
    Filed: March 16, 2009
    Date of Patent: October 30, 2012
    Assignee: Seagate Technology LLC
    Inventors: William Omar Liners, Mallika Roy, Francis Anthony McGinnity, Gavin Lee Brinkley

  • Magnetic recording device including a thermal proximity sensor
    Patent number: 7589928
    Abstract: A system includes a magnetic device for writing to and reading from a magnetic medium and a sensor disposed adjacent to the magnetic device and proximate to the magnetic medium. The sensor generates signals related to thermal variations in the sensor caused by changes in a distance between the magnetic device and the magnetic medium.
