ABSTRACT:
A micro-actuator assembly, which includes a first micro-actuator. The first micro-actuator includes: Two pivot spring pairs coupling to first stator and second stator. Two flexure spring pairs and pitch spring pair coupling to central movable section, which includes signal pair paths coupling to read-write head of a slider. The central movable section positions read-write head and conducts read-write head signaling. First micro-actuator electrical stimulus is through some of its springs. Micro-actuator assembly may include second micro-actuator with third stator and fourth stator interacting with central movable section. The second micro-actuator may also provide motion sensing, possibly indicating collision with the rotating disk surface being accessed. The invention includes head gimbal assemblies, actuator arms, actuator assemblies, voice coil assemblies and hard disk drives containing various embodiments of these micro-actuator assemblies.
