ABSTRACT:
A microactuator suspension assembly has a load beam structure with at least three layers of material in certain portions of the proximal area between the baseplate area and the spring area, the first and third layers comprising substantially inextensible metal, the second layer comprising extensible plastic, the plastic layer operating in shear when driven by an electrodynamically variable microactuator to make a microadjustment of the suspension.
