摘要
A head gimbal assembly (10) for a disk drive (1), having a load beam (28), a flexure (30), a portion of the flexure (30) being attached to the load beam (28), a slider (20) which includes a read/write head (22), and a collocated microactuator (24) which connects between the flexure (30) and the slider (20). The collocated microactuator (24) is a shear mode piezoelectric motor (25) for providing pure or nearly pure lateral movement to the slider (20), thus providing secondary actuation for the head gimbal assembly (10). ;A disk drive (1) and an actuator arm (2) including the head gimbal assembly (10) are also disclosed.
