Constrained dimple pad damper for disk drive head suspension

摘要

A disk drive head suspension including a load beam, a flexure on the load beam, and a load point dimple extending from the load beam toward the flexure. A constrained damper is located on the flexure and is engaged by the load point dimple. The constrained damper includes a layer of viscoelastic material on the flexure, and a metal constraining layer on the viscoelastic material. The flexure can be a co-located dual stage actuated flexure that includes a motor, and the constrained damper can be located on the motor.
