  • Heat source management in data storage device
    Patent number: 8891340
    Abstract: An apparatus and associated method is presently disclosed for a control circuitry capable of managing a heat source used in data storage applications. Various embodiments of the present invention are generally directed to a heat source directed at a data storage medium with a synchronization signal and a serial interface that are each selectively activated via a demultiplexed write gate signal. The selective activation allows for pulsed operation of the heat source resulting in reduced duty cycle and temperature during a write operation.
    Type: Grant
    Filed: September 16, 2013
    Date of Patent: November 18, 2014
    Assignee: Seagate Technology LLC
    Inventors: Michael H. Lennard, Robert Matousek

  • Sinking heat from an integrated circuit to an actuator
    Patent number: 8144432
    Abstract: An actuator for selectively positioning a portion of a communication channel formed by a cable circuit having a protuberant component connected at a proximal end to a flexible base, whereby the actuator defines a heat transfer surface operably disposed in thermal conductivity with a distal surface of the protuberant component for sinking heat from the component to the actuator.
