    摘要: A disc drive head actuator includes a suspension structure and a slider integrated with the suspension structure. The actuator is one of at least two actuator assemblies batch-fabricated on a common substrate. The head actuator may be fabricated using mircofabrication techniques. The head actuator may have a reduced size, including package height relative to conventionally manufactured disc drives. Using mircofabrication and/or batch fabrication techniques provides reduced tolerances, which allows for increased actuation forces and/or reduced power consumption. Some embodiments include four-bar linkage actuators, which increase lateral stiffness of the actuator, allowing for a precise motion of the head relative to a media surface.

    摘要: A method is used for moving a transducing head between tracks of a disc in a dual-stage actuation assembly. The dual-stage actuation assembly has a main actuator for coarse positioning of the transducing head and a microactuator for fine positioning of the transducing head. The method comprises accelerating the main actuator during coarse positioning of the transducing head and applying control pulses to the microactuator during coarse positioning by the main actuator to eliminate oscillation of the microactuator during and after coarse positioning.

    摘要: A suspension comprises a load beam having a leading portion and a trailing portion, a gimbal sheet mounted to the leading portion and forming a first pad, a second pad, and a displacement lever assembly including at least a first lever arm having a first end adjacent and connected to the first pad and a second end opposite the first end and connected to the second pad. The displacement lever assembly is configured to translate a linear displacement of the first pad to a differing displacement of the second pad. The suspension comprises a piezoelectric element attached to the first pad and extending across the second pad.

    摘要: Stability of a control system for a materials testing system using specified filter parameters is confirmed by inputting to the control system a test signal having a predetermined waveform, automatically monitoring the output of the materials testing system, and automatically comparing the output to a threshold. If the output exceeds the threshold, a first action is taken. If the output does not exceed the threshold, input of a command signal to the control system is permitted.
