Abstract
A disk drive head suspension includes a load beam designed for damping of torsion and sway resonance modes. The load beam includes a proximal end portion and a distal end portion, and the proximal end portion includes a proximal edge. The load beam also includes a strain-inducing feature that is formed into an upper planar surface of the load beam and extends from the proximal edge of the load beam. A flexure is attached to and supported by the load beam for carrying a magnetic head slider. A hinge attached to the load beam and to the base mounting structure, the latter of which is for coupling the head suspension to a disk drive actuation system. A damping element is on the load beam at the proximal end portion that spans across the strain-inducing feature and is adjacent to the proximal edge of the load beam.
