1,227,213. Magnetic storage apparatus SPERRY RAND CORP. 6 June, 1968 [9 June. 1967], No. 27006/68. Heading H3B. A magnetic storage array is formed b moulding a parallel assembly of rib members 42, Fig. 4, which are then bonded between rigid planar substrates 40a, 40b, printing parallel conductors 18, 20 on the outer surface of each substrate, joining corresponding conductors on each substrate by connectors 22 to form word drive lines, and inserting conductive wires 10 each plated with an anisotropic thin film in the spaces between the rib members. The assembly is overlaid with magnetic screen members 56, 56<SP>1</SP>. The stages of manufacture are shown in Figs. 7a to 7g in which the substrates 40a, 40b are formed of a copper laminate which is subsequently etched to provide the parallel conductors 18, 20, while the rib members 42 are formed by filling a mould 72 with an epoxy resin. The copper laminates are heat bonded to the rib members 42 while still in the mould and the mould subsequently removed. The ends of the laminar structure are machined away to expose the spaces between the rib members. Holes 59 are provided for the connectors 22 which may be in the form of a metallic coating within the holes or the metal teeth of a comb member 60. In the latter case the main body of the comb is detached after the teeth are inserted in the holes, the teeth being soldered to the respective conductors. A complete assembly is shown in Fig. 3 in which the array is mounted on a further substrate 48 and the ends of the drive lines and the plated wires terminate in respective connectors 54, 46. |
