  • Voice coil motor saturation detection
    Patent number: 10803892
    Abstract: A method includes monitoring an amount of power of a power supply being used by a voice-coil motor (VMC) during a seek operation, detecting that the amount of power has crossed a threshold during the seek operation, and modifying a subsequent seek operation in response to detecting that the amount of power has crossed the threshold.

  • Suppression of seek repeatable runout
    Patent number: 8730614
    Abstract: The disclosure is related to an apparatus and methods of suppressing seek repeatable runout. In a particular embodiment, a servo loop is disclosed. The servo loop includes a seek signal generation component that generates a seek trajectory acceleration signal. The servo loop also includes a STRRO suppression component that is coupled to the seek signal generation component. The STRRO suppression component injects STRRO suppression signals into the seek trajectory acceleration signal and outputs an STRRO suppressed seek trajectory acceleration signal.
