Abstract
744,197. Magnetic recording and reproducing apparatus. STANDARD TELEPHONES & CABLES, Ltd. Aug. 6, 1954 (Aug. 14, 1953], No. 22490/53. Class 40(2) [Also in Group XVI] An arrangement for feeding a magnetic tape past a transducer head compries a support over which the tape passes the support being provided with at least one duct through which gas is forced in such a direction as to maintain the tape spaced from the support and create a component of force in the plane of the tape which will move the tape over the support. As shown in Fig. 3 the tape is passed between air reservcirs 11 and reservoirs 12 and 13, ducts 14, 15, 16 being provided for driving the tape, the transducer head being located at 17. In the embodiment shown in Fig. 4 the tape is passed over supports 20, 21 which are provided with ducts suitably fed 'with air under pressure. Each transducer head 23 is provided with an air duct 24 for holding the tape slightly away from each head.
