Abstract:
1. A collocated, rotational, shear mode, piezoelectric micro-actuator comprising: at least one shear mode piezoelectric motor having a top surface and a bottom surface thereof, said piezoelectric motor top and bottom surfaces moving laterally with respect to each other when a control voltage is applied across a positive electrode and a negative electrode of the piezoelectric motor, said micro-actuator having top and bottom surfaces thereof and generating rotational displacement of said microactuator top surface relative to said microactuator bottom surface when the control voltage is applied across the piezoelectric motor electrodes; the micro-actuator being bonded to at least one a tongue of a flexure of a suspension and a read/write head of the suspension, and being coupled such that rotational movement of the micro-actuator about an axis causes corresponding rotational movement of the read/write head about said axis.
