Abstract
A head suspension includes a damping structure having at least one unconstrained surface. A reservoir is formed on the head suspension preferably from epoxy resin. Visco-elastic damping material is dispensed into the reservoir to form a damper on the head suspension. The damper and reservoir act to damp resonance mode vibrations of the head suspension.
