ABSTRACT:
Methods and apparatus for transducing information relative to an information carrier tape employ a cylindrical tape drive capstan rotatable about a line of intersection of two relatively stationary planes extending through the cylindrical capstan at right angles to each other. The tape is placed in a loop about the capstan and a first unsupported tape portion is formed at one side of one of the planes and at one side of the other of the planes, while a second unsupported tape portion is formed at the other side of that one plane and at the one side of that other plane. The tape is further formed into a first leg adjacent the loop at the other side of the other plane and into a second leg adjacent the loop at the other side of the other plane. The capstan is rotated to advance the tape and information is transduced relative to the advancing tape between the above mentioned curvature and the first peripheral region at the first unsupported tape portion and between that curvature and the second peripheral region at the second unsupported tape portion.
