ABSTRACT:
A disk drive suspension for mounting to the end of an actuator arm. The suspension includes a load beam having a base at a proximal end, a rigid region, a spring region between the rigid region and the base, a flexure for receiving and supporting a read/write head on a distal end of the load beam, a moving section, and a stationary section. The moving section is supported from the stationary section by at least 2 transversely extending resilient support beams. The support beams allow the moving section to pivot with respect to the stationary section. A microactuator is located on the load beam to pivot the moving section and shift the flexure including the read/write head along a transverse tracking axis in response to tracking control signals.
