1279718 Magnetic storage arrangements COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 19 Dec 1969 [30 Dec 1968] 62053/69 Heading H3B In a moving domain shift register, Fig. 1A, parallel propagation channels 3, 4 extend over a substrate, and are overlaid by a pair of zig-zag conductors 1, 2 which cross one another at 90 degrees and which cross the channels at 45 degrees. These conductors are pulsed to move domains along the channels, and the channels may be bridged as at 5, Fig. 1A, and Fig. 2 (not shown), to form closed loops or a long propagation path. Conventional conductors loops (not shown) are used to generate and detect the domains. Three channel structures are shown in Fig. 3, the left hand view showing a film of magnetic material 10 on a glass substrate 13, an apertured aluminium film 11 defining the channel shape, and insulating material 14, 15 separating the conductors 1, 2. In the central view of Fig. 3, the channel is formed of magnetically hard and soft films 10, 21 respectively, separated along the line of the channel by insulating material 12. In the right hand view of Fig. 3, the magnetic material 3 is deposited directly on to the substrate. The deposition of the films is accompanied by a magnetic field so that the films are magnetically anisotropic. |
