Abstract
A head suspension assembly comprising a visco-elastic coupling between a load beam dimple or protrusion and a suspension flexure to which a slider is rigidly coupled. The damping material is selected for a low static modulus, which reduces mechanical vibration by absorbing kinetic energy and releasing the energy as heat. The gimbaling function of the suspension is not significantly effected by the damping material because the damping effect occurs primarily when there is an undesirable relative velocity (movement with respect to time) between the dimple and the flexure.
