  • Method and apparatus for vibration damping of a suspended media read/write head
    Patent number: 8189440
    Abstract: A method of controlling a head for a recording medium includes determining that the head is in an inoperative state, and activating a damping arrangement in response to the determination that the head is inoperative. A movement of the head while the head is inoperative is sensed. The damping arrangement is used in response to the sensing step to exert a force upon the head to thereby damp the movement, a magnitude of the force being dependent upon a parameter of the movement.
    Type: Grant
