Head suspension including coupled flexure and damper constraint layer

摘要

A head suspension includes a damper having a constraint layer formed unitarily with the flexure. The damper is located on the same face of the load beam as the flexure and acts to damp resonance vibrations of the head suspension. The constraint layer overlays the damper and is coupled to the flexure by a narrow neck. In this way, the constraint layer can be aligned and attached to the beam along with the flexure. This facilitates alignment of the constraint layer. Further, the narrowness of the neck coupling the constraint layer to the flexure reduces transmission of vibrations from the load beam to the flexure.
