Abstract

Abstract A magnetic wire memory construction comprising a plurality of stacked memory planes, each memory plane being formed from two like-formed self-supporting and rigid metal sheets in opposed relation. The sheets have channels formed therein using precision batch fabricated metal sculpturing techniques, with certain of the channels being filled with insulative material. The dimensions and locations of the channels are chosen so that precisely located memory wire receiving tunnels and corresponding insulated drive line strips perpendicular thereto are formed when the sheets are placed together in opposed relation. Memory wire elements are inserted into the tunnels which protect and shield the elements and maintain them accurately positioned with respect to one another and to the drive line strips so as to permit achieving a memory of increased density and speed of operation.
