Abstract

A device for positioning a magnetic head to magnetic tape which includes two spaced apart plates connected by two front cylindrical outriggers and a rear threaded shaft. A magnetic head assembly is resiliently held between the threaded shaft and the two outriggers by a beam type plate spring having on a back side a nut or threaded follower which engages the threaded shaft. A stepper motor connected to a worm gear drives the threaded shaft into axial rotation which by being meshed with the follower raises and lowers the follower, and thus the magnetic head, with respect to the threaded shaft. The magnetic head provides two V-shaped regions which guide head movement on one outrigger and a flat bearing surface on the opposite side to slide on the second outrigger, forming a precisely set three point guiding of the magnetic head.
