Low translational load suspension assembly

摘要

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.

1. A suspension assembly for a storage device, comprising:
a base plate to attach to an actuator arm; and a load beam movably attached to the base plate by two actuators angled with respect to one another and having proximal ends closer to one another than distal ends, the actuators adapted to rotate the load beam about a rotation axis through a center of rotation substantially at a center of mass of the load beam, wherein the center of rotation of the load beam is closer to the distal ends of the actuators than the proximal ends and wherein the rotation axis is separated from a transducer head.
