Abstract
A microactuated disk drive suspension for supporting a slider at a disk includes a load beam extending in a plane and having on a common axis a base section adapted for mounting to an actuator, a spring section and a beam section carrying a flexure and the slider thereon. The suspension has relatively movable proximate and distal portions on the common axis that are joined by a bending system cantilevered from the proximate portion and including a cantilevered bending motor opposed to the common axis and having a laterally bendable unsupported region. A cantilevered laterally bendable load assist structure defined by the suspension edges is provided arranged to block undue loading of the bending motor unsupported region.
