In a system mounting a magnetic transducer on the end of a thin leaf for sweeping motion displacement laterally to a track on a record surface, the present invention utilizes elements arranged as reversely deflectable leaf portions so as to maintain the transducer in substantially undeviating (normal) orientation with respect to the record surface. In one embodiment, the cantilevered leaf is composed of inner and outer (inboard and outboard) piezoelectric ("bimorph") bender elements having opposite polarizations and being cross-wired to produce the reverse deflections desired. The electrodes of the elements may also be divided longitudinally and coupled to bias voltage sources to provide controlled correction of azimuth error.
