Abstract
A disk drive suspension including a load beam having a rigid region, a base on a proximal end of the load beam and a flexure for receiving and supporting a read/write head on the distal end of the load beam. A microactuator on the load beam moves the flexure and read/write head about a tracking axis with respect to the rigid region. The microactuator includes a moving pole member mounted to the flexure, a stationary pole member mounted to the rigid region of the load beam adjacent to the moving pole, and coils around the stationary pole member.
Claims18
A disk drive suspension, including:
- a load beam having a rigid region, proximal and distal ends, and a spring region between the proximal end and the rigid region;
- a mounting region on the proximal end of the load beam;
- a flexure on the distal end of the load beam, the flexure configured for receiving and supporting a read/write head;
- and
- a microactuator on the rigid region of the load beam, the microactuator responsive to tracking control signals for moving the flexure along a tracking axis with respect to the rigid region.
A magnetic disk drive suspension, including:
- a load beam having a rigid region, proximal and distal ends, and a spring region between the proximal end and the rigid region;
- a mounting region on the proximal end of the load beam;
- a flexure at a distal end of the rigid region of the load beam, the flexure configured for receiving and supporting a magnetic read/write head;
- and
- an electromagnetic microactuator including at least two coils on the rigid region of the load beam, the coils generating magnetic fields in response to tracking control signals and causing the flexure to move along a tracking axis with respect to the rigid region.
