Filed: 1960-09-23
Abstract: 964,700. Magnetic thin film storage devices. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Aug. 3, 1961 [Sept. 23, 1960], No. 32751/60. Heading H3B. An information storage device includes a magnetic storage film, at least one driving conductor forming an elongated loop of which one side is arranged close to the film, a bistable switch core adjacent the ends of the loop and linked by a wire joining the ends of the loop, and means for switching the core to induce a current in the driving conductor. In one embodiment, magnetic films 7 are supported on back-to-back pairs of substrates 1 and have conductor structures 3, 4, including driving conductors 5 and sense conductors (not shown), passing close to them, as described in Specification 942,567. Further driving conductors 6 are provided as shown and in the open end of each loop is placed a bi-stable switch core 13 linked by a wire 12 which closes a loop. Cores 13 form a two-dimensional matrix and are linked by column conductors 14 and row conductors 15. To enter information to the store a particular core 13 is switched by energization of appropriate conductors 14, 15, whereupon a current is induced in a conductor 6. Simultaneously, a current pulse is passed through a conductor 5 in structure 3 or 4 to switch a particular area of the film. For readout core 13 is switched back to energize conductor 6 in the reverse sense, but the arrangement for energizing conductors 14, 15 is such that the rate of switching back is increased to give a larger current in conductor 6. Alternatively, information may be stored by the method described in Specification 880,383. If conductor structure 4 is dispensed with (Fig. 3), conductor 6 may be connected at the closed end of the loop to a foil 17 between the substrates of each pair, or to the substrates themselves if they are conductive, a separate core 13 being provided for each half of the loop. A substrate coated on both sides may be used in a similar manner. Switch cores 13 are mounted on a plate having good electrical and heat-conducting properties.
