A head positioning transducer is disclosed for use with a rotating drum assembly for scanning a magnetic tape along a plurality of adjacent helically positioned record tracks, wherein the transducer includes a permanent magnet field assembly and a drive coil positioned adjacent thereto mounted on a cantilevered beam, at one end of which a playback head is mounted, such that a drive current supplied to the coil produces a field which interacts with the field of the magnet, causing a force on the coil and beam, resulting in controlled movement of the head transverse to the record tracks.
