<p>PROBLEM TO BE SOLVED: To provide a mass balanced flexure gimbal for head gimbal assembly sway mode control.SOLUTION: Approaches to a mass balanced flexure gimbal assembly controls a sway mode of a load beam portion of a suspension of a head gimbal assembly (HGA) of a hard-disk drive (HDD). The sway mode of an object is a mode which is excited when a head slider is actuated by a plurality of piezoelectric actuation devices of a secondary actuation system. The suspension comprises a mass attached to a suspension flexure and configured for balancing moment force around a gimbal, around which the slider rotates when micro-actuated. The mass is located on a side of the slider opposing a side on which the piezoelectric actuation devices are mounted, to counteract the mass of the piezoelectric devices.</p> |
