Patent ID: 7333298

Claim:
A magnetic head actuator in a magnetic disk drive unit, which is mounted at a distal end of an arm extending from a voice coil motor, and coupled to a suspension having a magnetic head slider mounted at its distal end for providing swing motion of the slider, said actuator comprising: a stator section secured to the arm distal end; an attachment section secured to the arm distal end together with the stator section; metallic micro-beams extending from the attachment section and shaped by bending, each of the micro-beams including at least one fold; a rotor section supported for swing motion by the micro-beams; a permanent magnet disposed in the stator or rotor section; and a coil disposed in the rotor or stator section, wherein electric current is conducted through the coil in the magnetic field created by the permanent magnet for causing the micro-beams to be displaced for inducing swing motion of the suspension secured to the rotor section and the magnetic head slider mounted thereon.
