A reversible tape transport moves a record tape, such as magnetic recording tape, between two rolls which function alternately as supply and takeup Rolls. One or more magnetic recording and/or reading transducers scan longitudinally independent parallel tracks on the tape. Mechanism for locating the heads in alignment with desired tracks is interlocked with the drive for the transport such that the transducers will follow even numbered tracks in one direction, and odd numbered tracks in the other direction of movement of the tape, and the positioning mechanism is self-correcting in the event that it should get out of phase with this desired relationship.
