Abstract:
1. A dual stage actuated suspension for a disk drive, the suspension comprising a load beam and a flexure attached to the load beam, the flexure comprising a gimbal and a flexible circuit, wherein the flexible circuit comprises a metal support layer, an insulating layer thereon, and a signal conducting layer thereon, the suspension further comprising: a microactuator operatively connected from a relatively fixed portion of the suspension to a portion of the flexible circuit which is movable relative to the load beam, the movable portion of the flexible circuit being attached to a head slider mounted thereto such that activation of the microactuator pushes against the flexible circuit thereby effecting fine movements of the head slider for fine position control of the head slider; wherein the load beam has an aperture therethrough that is larger than the microactuator, the microactuator extending in height away from the flexure and at least partially through said load beam aperture such that the microactuator extends in height at least partially to a side of the load beam that is opposite to a side of the load beam at which the flexure is mounted.
