Abstract
Various embodiments concern a dual stage actuation suspension that comprises a loadbeam having a load point projection. The suspension further comprises a gimbal assembly having a point of contact that is in contact with the load point projection such that the gimbal assembly can gimbal about the load point projection. The gimbal assembly is cantilevered from the loadbeam and has an axis of rotation aligned with the load point projection and the point of contact. The suspension further comprises a pair of motors mounted on the gimbal assembly and positioned proximal of the point of contact. The pair of motors is mounted between a tongue and a pair of spring arms to rotate the tongue about the point of contact and the load point projection. The loadbeam further comprises a void into which the pair of motors extends.
