Abstract

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.

First claim

What is claimed is:

1. A disk drive head suspension, including:
a load beam;
a flexure on the load beam;
a load point extending between the load beam and flexure; and
a constrained damper between the load beam and the flexure, wherein the constrained damper is engaged by the load point and includes:
a layer of viscoelastic material on one of the load beam and flexure; and
a constraining layer on the layer of viscoelastic material.

2. The disk drive…
