Mechanism for moving recording heads across computer tapes.

摘要

A mechanism (10) for moving a magnetic read/write recording head (12) across a tape (14) storage medium. A linear actuator (22) drives an output shaft which carries a cable connector (44). A flexible cable (46) is connected with the cable connector (44) at one end and at the other end with an elevator bracket (58) which carries the recording head (12). The cable (46) is bent through a 90° bend between its ends along an arcuate guide surface (54). The elevator bracket (58) moves up and down across the tape (14) on guide pins (66). A spring (78) maintains the cable (46) under tension to translate horizontal extension and retraction of the actuator shaft (38) into corresponding vertical movement of the tape head. The use of a cable (46) reduces the application of moments to the head (12) and avoids applying rotational forces.
