Abstract
A microactuator suspension supports a slider. The microactuator suspension has at least a first resilient support extending from a slider attachment pad to a suspension arm attachment pad. The slider attachment pad forms a clip which contacts the slider on side faces of the slider, and the microactuator adds little or nothing to the vertical thickness of the head gimbal assembly. The suspension arm attachment pad attaches to the gimbal with an attachment bridge which is longitudinally balanced relative to the gimbal point and relative to the air bearing centroid of the slider. The resilient supports may be beams having ends which are longitudinally spaced relative to the gimbal point, to the air bearing centroid, and to the attachment bridge to minimize moments and localized stresses on the beams. Dual beam and multiple beam arrangements are provided. The microactuator suspension further provides vibration attenuation at the slider of vibrations experienced by the suspension arm.
