ABSTRACT:
A disk drive suspension has a load beam having a base, a flexure for carrying a slider, and a mount plate. The suspension mount plate has a first portion attachable to an actuator and movable by the actuator as the primary shifting force on the load beam, suitable for larger positioning movements. A second portion of the mount plate is attached to the load beam base and is movable relative to the mount plate first portion. A microactuator moves the second mount plate portion relative to the first mount plate portion as a secondary shifting force on the load beam, suitable for very small positioning movements.
