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.

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.
Apparatus comprising:
- an actuator arm to position a transducer head relative to a rotating media, the actuator arm attached to a baseplate;
- and
- at least two actuators angled with respect to one another and having proximal ends closer to one another than distal ends, the actuators adapted to rotate a load beam relative to the baseplate about a rotation axis through a center of rotation, wherein the center of rotation of the load beam is closer to the distal ends of the actuators than the proximal ends and the load beam and has a center of mass located substantially at the center of rotation, wherein the rotation axis is separated from the transducer head.
A storage device comprising:
- a base plate with a first end attached to an actuator arm;
- and
- a load beam movably attached to a second opposite end of the base plate by two actuators angled with respect to one another and having proximal ends closer to one another than distal ends, wherein the load beam has a center of mass and a center of rotation at a common point separated from a transducer head and the center of rotation is closer to the distal ends of the actuators than the proximal ends.
