    摘要: A micro-actuator that reduces suspension tongue stiffness and a method of manufacturing the micro-actuator are disclosed. In one embodiment, the micro-actuator has a base piece with two arms extending from the base piece. The electric contact pads for the arms are situated on the exterior of the arms at the end opposite the base piece. In one embodiment, the electric contact pads are electrically coupled to the same connection plate that the magnetic read/write head is coupled to, reducing the number of connection traces.

    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.
