Abstract
1,165,513. Magnetic storage apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 24 May, 1968 [27 May, 1967], No. 24909/68. Heading H3B. A magnetic storage matrix is formed by inserting annular cores 1, into circular recesses 3 in a metal plate 2, each recess containing at least one plate projection 5 which extends through the associated core and above the plate surface, and the plate having grooves 7 of greater depth then the recesses. Subsequently, the recesses, grooves, and the plate are coated with a layer of insulating material e.g. epoxy resin, the extremities of the plate projections being exposed. The plate projections are then interconnected by wiring such as printed conductors, and the bases of the plate projections electrically separated from each other by removing material from the surface of the plate opposite the recesses to an extent such as to expose the grooves. The recesses and grooves may be formed either by etching or a compression and extrusion process, and the material is removed by either etching or grinding. Suction holes (11), Fig. 2 (not shown) are provided in the recesses to facilitate introducing the cores.
