Abstract
An improved resonance and non-operating shock performance, low debris-generating disk drive suspension head gimbal assembly for positioning a head at a disk in which the load beam body is locally relieved or deflected to provide shelter for the portion of the flexure usually in the path of the lift arm against debris causing contact of the lift arm with the flexure edges and distortion of the flexure from lift arm contact in a load beam unsupported condition. The local relief reduces the load beam mass for high shock performance; the modification of the load beam contour improves stiffness and thereby improves resonance qualities.
