Abstract
Apparatus for positioning a control object, such as a microactuator used to position a read/write transducer adjacent a data storage medium. In accordance with some embodiments, a piezoelectric transducer (PZT) element is adapted to induce rotational displacement of the control object in a bending mode of operation. The PZT element has a plurality of piezoelectric material layers and a plurality of electrically conductive layers interposed between the piezoelectric material layers. The piezoelectric material layers include a first subset of active layers and at least one non-active layer.
