  • Low translational load suspension assembly
    Patent number: 9286923
    Abstract: Implementations described and claimed herein address the foregoing problems by providing a suspension assembly used in a storage device to support a transducer head, wherein the suspension assembly comprises a base plate for attaching to an actuator arm and a moving portion movably attached to the base plate. The base plate is fixed and/or clamped to the actuator arm and the moving portion adapted to rotate about a center of rotation. The moving portion is adapted to have a center of mass of its moving mass substantially close to its center of rotation. In one implementation, a counter-weight is attached to the moving portion to move the center of mass of its moving mass substantially close to its center of rotation to minimize inertial loads to the system during suspension actuation.
    Type: Grant
