摘要： A pure rotary microactuator comprising a spring assembly etched within a silicon substrate is disclosed. A first piezoelectric device is coupled with a first portion of the spring assembly and a second piezoelectric device coupled with a second portion of the spring assembly. The first piezoelectric device changes shape in response to an electrical input signal, and this change in shape provides a first push force to the first portion of the spring assembly in a first direction. The second piezoelectric device also changes shape in response to the electrical input signal, and this change in shape provides a second push force to the second portion in a second direction, which is different from the first direction. The combination of the first and the second push forces rotates the spring assembly with respect to the silicon substrate.

摘要： A hard disk drive has a flexible cable and a flexible cable damper positioned adjacent to but separate from the flexible cable. The damper is a thin film loop with a damper patch that is completely independent of the flexible cable. The damper strip is a non-signal carrying substrate and has the constraint layer attached to it opposite the flexible cable. Both the damper and flexible cable extend in an arcuate configuration from the base to an integrated lead suspension tail extending from the actuator.
