Abstract

A magnetic tape drive comprising a magnetic head for reading and/or writing a magnetic tape passing thereover. The magnetic head is positioned for tracking a select track or series of tracks on the tape. The head is generally fixed to a frame or can be rendered stationary with respect to a frame. A source of magnetic tape, such as a reel, is positioned to a side of the magnetic head, while a collector of magnetic tape, such as a second reel, is also positioned to a side of the magnetic head. For tracking, at least one tape actuator is positioned between the magnetic head and either the source and collector. The tape actuator is comprised of a base with a surface portion defining a tape path over which the magnetic tape passes. At least the base of the tape actuator is attached to the frame, or may be rendered stationary with respect to the frame. The tape actuator also includes at least one movable portion adjacent a first edge of the tape path and a corresponding counter-balancing portion adjacent the opposite (second) edge of the tape path. The movable portion is coupled to or interfaces with a drive for imparting movement to the movable portion in a direction transverse to the tape path. The movable portion has a hardened engagement portion for engaging the first edge of a tape in the tape path. The counter-balancing portion is resiliently movable in a direction transverse to the tape path and also has a hardened engagement portion for engaging the second edge of a tape in the tape path.
