Abstract
A magnetic tape head actuator comprising an actuator motor having a threaded output shaft and a bracket for holding a magnetic tape head. The bracket includes two spaced apart supports that have aligned passageways. The output shaft extends through the passageways. The diameter of the output shaft and the passageways are matched for stabilized sliding movement to allow the actuator bracket guided movement back and forth along the output shaft. The actuator further including a nut with a threaded passageway attached to the actuator bracket. The output shaft extends through the passageway of the nut and is in threaded engagement therewith so that rotation of the output shaft moves the actuator bracket along its length. The nut has a slot that extends axially of the threaded passageway and that is in communication therewith. An elastic member encircles the nut in resilient inwardly pressing relationship intermediate the ends of the slot. The dimensions of the slot and the pressure of the encircling member is such that the nut is elastically deformed to urge the passageway threads of the nut against the threads of the output shaft.
