Abstract
A disk drive suspension has laterally separated mount plate cooperating structure of a pair of spaced, left and right hand continued extents defining engagement structures extending into the vertical plane of the suspension hinge portion, and laterally separated beam portion cooperating structure of left and right hand continuations defining cooperating engagement structures also extending into the vertical plane of the hinge portion and overlapping the mount plate extents to block their relative vertical movement in one direction but not the other so that rotation of the beam portion relative to the mount plate is limited by this selective engagement of the cooperating structures, while the hinge portion is untrammeled by the cooperating structures and the suspension has increased torsional stiffness without an increase in suspension vertical stiffness or has a decrease in suspension vertical stiffness without a decrease in torsional stiffness.
