Abstract

A plurality of magnetic strips 10 is deposited on a soluble substrate 12, e.g., water soluble salt. An array of wires 14 for establishing and sensing magnetic states in the magnetic films is placed on the magnetic films as in drawing 13. The assembly is immersed in a solvent for the substrate 12 of drawing A. Upon dissolution of the substrate, each magnetic film curls around the respective intersection of wire array 14 to make a toroid 10A. The entire toroid memory array in accordance with this batch fabrication technique is shown in drawing D. The final array can be potted in a supporting member. Such is effected after appropriate washing and drying and heat treating to enhance the magnetic material and the magnetic joining of the overlapped portions of each magnetic film 10.
