Abstract: 1,023,627. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 26, 1964 [Nov. 21, 1963], No. 43506/64. Addition to 998,891. Heading H3B. [Also in Division H1] The tubular storage device described in the parent Specification is modified by the use of hole pairs for the conductors B in the form of two parallel slits 18 arranged longitudinally of the tube 12, each conductor B being made of strip material. The tube is formed by a magnetic U-shaped trough 14 and a magnetic closure plate 16, the same or different materials being used. The magnetization characteristic of the magnetic material need not be rectangular.
