HEAD SUSPENSION ASSEMBLY WITH PIEZOELECTRIC BEAM MICRO ACTUATOR

摘要

A micro actuator driven load beam mechanism for use in a headsuspension assembly is disclosed. The mechanism includes a load beamincluding a proximal end portion and a distal end portion, a hinge portionconnecting the proximal and distal end portions of the load beam for permittingrelative movement therebetween, and a piezoelectric beam connecting theproximal and distal end portions, the piezoelectric beam being selectivelyenergizable to effect relative movement between the proximal and distal endportions. The load beam includes a pocket for holding at least one end of thepiezoelectric beam. The piezoelectric beam and the pocket may be inclinedrelative to a hinge plane to control the load beam twist and minimize the altitudevariations of the beam tip.
