The tape is enclosed in a housing having substantially identical opposite ends each of which is adapted to be received in a tape player. Means engaging the tape are interposed between the opposite ends of the housing for rotating the tape 180.degree. in a first direction and 180.degree. in the opposite direction whereby opposite sides of the tape are exposed at the opposite ends of the housing permitting intelligence to be recorded and "played back" on both surfaces of the tape.
