Abstract
A gimbal assembly of a dual-stage microactuator is provided with a remotely-located piezoelectric transducer (PZT) and at least one actuation strut connecting an asymmetrical amplification structure supporting the PZT to a tongue supporting a slider, such that the movement of the PZT over the asymmetrical amplification structure is amplified by the asymmetrical amplification structure and at least one actuation strut into rotation of the tongue and slider. A plurality of actuation struts connect opposing sides of the asymmetrical amplification structure with opposing sides of the tongue, which causes the tongue to rotate about a central portion of the tongue upon which a dimple of a supporting loadbeam contacts the tongue.
