Abstract
A magnetic head is attached to a hollow carriage which surrounds a hollow cylindrical positioner post rigidly secured at one end to a frame element of a tape drive. Precision ball bearings mounted to the carriage engage the outer surface of the cylindrical positioner post at longitudinally and circumferentially spaced locations. A positioner shaft extends through the positioner post and a tracking nut in one end of the carriage is screwed over a threaded segment of the shaft. A pin extends from the carriage and is longitudinally slidable in a recess in an anti-rotation block mounted on the frame element. A stepper motor can drive the shaft to reciprocate the carriage toward and away from the frame element thereby moving the head traversely with respect to a length of magnetic tape. An adjustable stop on the post limits movement of the carriage toward the frame element.
