Abstract
Apparatus for positioning a transducer head in a prescribed relationship relative to a selected track on a recording medium. The apparatus includes a lead screw that is threadedly coupled to a bracket for supporting the transducer head, whereby a controlled rotation of the lead screw functions to move the transducer head along the surface of the recording medium, to the prescribed position. Rotation of the lead screw is controlled by a geneva mechanism that includes geneva wheel coupled to the lead screw and a geneva driver driven by a reversible d-c motor. Each revolution of the geneva driver rotates the geneva wheel, and thus the lead screw, through a prescribed angle, such that the transducer head is moved along the recording medium by a prescribed amount, such as one track spacing.
