ABSTRACT:
A disk drive suspension has a base portion, a spring portion, and a beam portion carrying a slider at a disk. The base portion is a laminate of two inextensible outer layers and an inner layer that is extensible in shear. Microactuators that expand or contract are attached by their opposite ends in angled or parallel relation to the respective outer layers to shift the outer layers relative to each other as a function of shearing in the inner layer to shift the slider at the disk.
