ABSTRACT:
Apparatus for automatically adjusting the azimuth angle of a transducer head relative to a media recording surface when the transducer head is driven in a non-radial path about the media recording surface with a transducer head supported by a positioning support shaft located within a head carriage. The head carriage receives drive forces from a worm gear and the positioning support shaft is attached to a control shaft and a positioning shaft for azimuth angle alignment during head carriage movement.
