  • Characterizing a sensing circuit of a data storage device
    Patent number: 9953674
    Abstract: A data storage device is disclosed comprising a disk, a head for accessing the disk, and a sensor for generating an alternating sensor signal. The sensor is disconnected from an input of a sensing circuit and while the sensor is disconnected an alternating calibration signal is injected into the input of the sensing circuit, wherein the alternating calibration signal comprises a predetermined offset and amplitude. A response of the sensing circuit to the alternating calibration signal is evaluated to detect at least one of an offset and a gain of the sensing circuit.
    Type: Grant
    Filed: June 27, 2017
    Date of Patent: April 24, 2018
    Assignee: Western Digital Technologies, Inc.
    Inventors: Paul Dylan Sherman, Tuyetanh Thi Dang
