    摘要： A micro-actuator for a head gimbal assembly includes a support frame including a bottom support adapted to be connected to a suspension of the head gimbal assembly, a top support adapted to support a slider of the head gimbal assembly, and a leading beam that couples the bottom support and the top support. The leading beam includes weak points or notches that allow the top support to rotate about a rotational axis in use. A first PZT element is mounted between first sides of the top and bottom supports, and a second PZT element is mounted between second sides of the top and bottom supports. The first and second PZT elements are excitable to cause selective rotational movement of the top support about the rotational axis in use.

    摘要： A rotational micro-actuator (20) used in hard disk driver is disclosed. It comprises a frame (21) approximately in the shape of letter “S” and PZT pieces (28, 29) attached to said frame (21), wherein said frame (21) is formed with a central coupling portion (213) by which the micro-actuator (20) is coupled to a suspension tongue (177), and two pieces of said PZT (28, 29) are arranged in central symmetry manner about said central coupling portion (213) such that said micro-actuator (20) can rotate about said central coupling portion (213) in response to the driving signals applied to said PZT pieces (28, 29), thus cause the displacement of the head element secured to the micro-actuator (20) so as to achieve the fine positioning of the head element. With above configuration, the micro-actuator of this invention will not cause the resonance of the suspension base plate during operation. Thereby the servo bandwidth of the hard disk driver is expanded.

The micro-actuator includes a metal frame including a top support to support the slider, a bottom support to connect to the suspension, and a pair of side arms that interconnect the top support and the bottom support. The top support includes a rotatable plate and connection arms that couple the rotatable plate to respective side arms. A PZT element is mounted to each of the side arms. Each PZT element is excitable to cause selective movement of the side arms. The suspension includes a load beam having a dimple that engages and supports the rotatable plate in use.

    摘要： A system and method for improving piezoelectric micro-actuator operation by preventing undesired micro-actuator motion hindrance and by preventing micro-actuator misalignment during manufacture. A shim element is interposed between an electric circuit assembly and a lower portion of an actuator frame. The electric circuit assembly has a generally ‘O’-shaped portion configured so that an upper portion of said actuator frame is able to protrude through the ‘O’-shaped portion. The shim element is coupled between the electric circuit assembly and the lower portion of the actuator frame.
