The tape is wrapped about the hub to form a coil and extends from the innermost wrap in the coil through a slot in the hub, across the central opening and then around one side surface of the coil to the outermost wrap of the coil. A tape drive mechanism, tape guides and a transducer of a recording and/or playback machine can be positioned in the central opening to pull tape through the slot from the inner wrap of the coil and accurately guide the tape along a path past the transducer.
