摘要： A precise positioning actuator for precisely positioning at least one head element is provided with a base and a pair of movable arms capable of displacing in response to a drive signal applied to the actuator. The pair of movable arms extend from the base for catching a head slider with at least one head element in a space between the pair of movable arms. Each of the pair of movable arms includes an arm member made of an elastic sintered ceramic and having substantially the same cross sectional shape from a root thereof to a top end thereof, a piezoelectric element formed on a side surface of the arm member and a protrusion additionally formed on an inside surface of the arm member near its top end section. The protrusion has tapered surfaces. Side surfaces of the head slider are adhered to the inside surfaces of the arm members at the protrusions and within regions between the protrusions and top ends of the arm members.

摘要： A system and method are disclosed for using a test slider to test the resonance performance of a head gimbal assembly. The test slider has a two-stripe air-bearing surface to allow the test slider to glide above a surface and a block with a mass equal to the combined mass of the electrical slider and the micro-actuator. The leading edge of the slider is tapered and has a main air groove to facilitate gliding. A back step on the side of the test slider opposite the air bearing surface maintains a parallel gap between the slider and the suspension tongue of the head gimbal assembly.

摘要： A thin film piezoelectric (PZT) micro-actuator is disclosed. Two thin film pieces of PZT are couple to a slider support frame. The slider support frame has a slider support connected by a leading beam to a base. The two thin film pieces of PZT connect the slider support to the base. Applied voltage causes the thin film pieces of PZT to contract or expand, moving the slider support in relation to the base. The thin film pieces of PZT can be single or multiple layers. The thin film PZT micro-actuator can be coupled to the suspension by anisotropic conductive film, with the thin film pieces of PZT between the slider support frame and the suspension. Alternately, the thin film PZT micro-actuator can be coupled to the suspension with the thin film pieces of PZT exterior to the slider support frame and the suspension.
