A microactuator device for effecting fine positioning of a transducing
head with respect to a selected track on a disk having: a C-shaped
piezoelectric element having opposite ends, wherein one end of the
piezoelectric element is affixed or connected to one end of the slider,
and the other end is affixed or connected to the flexure member for
obtaining rotational movement of the piezoelectric element to enable
faster and more accurate tracking of the disk by head transducer.
Alternately, the C-shaped piezoelectric element has one end affixed or
connected to suspension mount plate and other end affixed or actuator arm
to obtain larger head movement for further enhanced track following. The
C-shaped element could be multiple layered or be shaped like a horizontal
or vertical spiral to further increase the element and head movement and
tracking accuracy along with faster seek and travel.
