ABSTRACT:
A mechanism for moving a magnetic read/write recording head across a tape storage medium. A linear actuator drives an output shaft which carries a cable connector. A flexible cable is connected with the cable connector at one end and at the other end with an elevator bracket which carries the recording head. The cable is bent through a 90.degree. bend between its ends along an arcuate guide surface. The elevator bracket moves up and down across the tape on guide pins. A spring maintains the cable under tension to translate horizontal extension and retraction of the actuator shaft into corresponding vertical movement of the tape head. The use of a cable reduces the application of moments to the head and avoids applying rotational forces.
