A head flexure assembly having a flexure with a built in microactuator is disclosed.
The flexure is divided into four portions: a base plate portion for attaching the
flexure to an actuator arm; a load beam portion for suspending a transducing head;
a parallelogram portion connecting the load beam portion and the base plate portion
and allowing for the translational movement of the load beam portion with respect
to the base plate portion; and a driving frame portion. The parallelogram portion
has two substantially parallel members that attach the base plate portion to the
load beam portion. The parallel members limit the movement of the load beam portion
relative to the base plate portion to translational movement. The driving frame
portion has piezoelectric element that in response to a control signal produces
a force, orthogonal to the flexure's longitudinal axis, between the base plate
portion and the load beam portion.
