    Abstract: A tape transport apparatus in which the take-up and take-off reels are simultaneously driven by surface engagement of a capstan with the outermost tape layer on each reel. The reels are rotatably mounted on carriages which are translationally slidable with a minimum of friction and are urged towards each other by springs to provide substantially equal compressive forces at the two zones of tape engagement. The capstan has little or no resilient material on its peripheral surface to permit tape slippage under the action of a brake which, due to the provision of a unidirectional clutch, is effective only on the supply side of the apparatus. The brake is designed so that the braking torque changes substantially in direct proportion to the distance of the axis of the supply carriage from the capstan periphery. In this fashion the tape tension in the span between the above two zones of tape engagement is maintained virtually constant.
