摘要： A method and mechanism for visually inspecting both sides of components for a hard disk drive are disclosed. The components are stored in the containment units of a packing tray, with an exchange tray with matching containment units placed above and in contact with the packing tray. The components could be magnetic read/write heads, head gimbal assemblies, or other parts of hard disk drive. The two trays are rotated, using gravity to cause the components to move from the packing containment unit to the exchange containment unit.

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 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.
