Abstract

X, Y and sense wires are embedded in an insulating support 10. The wires are arranged so that they define a number of intersections, trix fashion. Pairs of apertures 11 are formed at selected intersections at which it is desired to store information.

Storage Device

X, Y and sense wires are embedded in an insulating support 10. The wires are arranged so that they define a number of intersections, trix fashion. Pairs of apertures 11 are formed at selected intersections at which it is desired to store information.

Magnetizable material 13 is deposited on the surface of the support and in the apertures. Thus, each intersection having an associated pair of apertures is surrounded by magnetizable material to form a rectangular toroid 14. The toroid 14 is recessed from the body of the support 10. This enables the magnetizable coating of the latter to be removed readily to minimize magnetic interaction between toroids.
