Abstract
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.
