A tape transport apparatus for delivering a tape at high speed and under a constant tension within a precise plane of tape travel comprises: (a) a rotatably mounted tape supply; (b) a rotatably mounted tape take-up; (c) a first moving rim drive belt cooperating with the take-up and including a guide for placing the moving tape onto the rim drive belt, the rim drive belt positioned to carry the moving tape to the tape take-up and apply it to the tape take-up; (d) a drive for rotating the tape take-up; (e) the guide comprising a roller having a crowned drive surface for centering the rim drive belt and the tape thereon during rotation thereof in the tape winding plane of the tape take-up for applying the tape precisely within the desired plane; and (f) a tape tensioning device for maintaining constant, predetermined tension on the tape, said tape tensioning device rotating the tape take-up at a predetermined, slightly faster surface speed than the speed at which the tape is being supplied thereto from the tape supply.
