Abstract

877,373. Magnetic structures. VECTRON ELECTRO-PHYSICS Ltd. March 10, 1960 [Feb. 1, 1960], No. 3510/60. Class 38 (2). [Also in Group XXXVIII] Marks, for example stripes, 17, 18, 19, numbers, 25, 50, 75, or dots, are made on the base of a magnetic tape and are then covered with a coating of magnetic material. The marks may be printed or painted on the base and may be of material distinguishable in colour or may reflect or absorb E.M. waves differently from the magnetic coating so as to be responsive to electronic or photo-electric devices. They may be metallic so as to have eddy currents induced therein by an energizing coil which reacts to the eddy currents. The sensing device may respond to cause a change in the track being read or may operate as a footage indicator or counter.
