Abstract
1,046,154. Magnetic storage apparatus. NIPPON ELECTRIC CO. Ltd. Feb. 18, 1965 [Feb. 18, 1964], No. 6992/65. Heading H3B. A magnetic storage matrix comprises a plurality of parallel non-magnetic conductors 12, Fig. 1, each coated with a thin ferromagnetic storage film having a circumferential easy axis of magnetization, the conductors being housed in parallel grooves 13 formed in two thermoplastic sheets 15 which are assembled in faceto-face relationship with their plane surfaces in contact, each sheet carrying slender conductors 11 which extend orthogonally of the coated conductors 12. A thin insulation layer is provided on the inner surface of each sheet. Printed strip conductors 11 spaced at uniform intervals and surface mounted are used as shown, but in a modification, Fig. 2 (not shown), thin wires 21 are embedded in each sheet and are positioned in groups so as to produce distinct local magnetizations along the coated conductors 12 when energized. In the arrangement shown the outer strip conductors 16 serve as driving wires, and the inner strip conductors are connected and provide short-circuit turns about two coated conductors 12 which serve to prevent unwanted magnetic disturbances. Alternatively the outer strip conductors 16 may be joined together and the inner conductors serve as the driving wires, or the short-circuited conductors may be omitted. A complete matrix is described, Fig. 3 (not shown), in which the magnetic coated conductors 12 are connected to terminals 31, 32 printed on a pair of opposed sides of an insulated frame 33, and the ends of the thermoplastic sheets are adhered to the other pair of frame sides. Terminals 36, 37 are provided for the driving wires. The storage matrix in the frame window is shrouded by insulating or non-magnetic-metal plates 39.
