A head gimbal assembly for a disk drive. The head gimbal assembly includes
a load beam defining a longitudinal axis. The head gimbal assembly further
includes a flexure with a portion of said flexure being attached to said
load beam. The head gimbal assembly further includes a slider including a
read/write head. The head gimbal assembly further includes a collocated
microactuator which connects between said flexure and said slider for
providing pure or nearly pure lateral movement to said slider in a plane
of motion that includes the longitudinal axis. The collocated
microactuator is a shear mode piezoelectric motor and disposed between the
slider and the load beam along an axis disposed orthogonal to the
longitudinal axis.
