Abstract

Wire patterns 10 and 12 of drawings A and B are established as sense or drive lines on insulation 11 and 13, respectively. A composite of intersecting wires is shown in drawing C. Such is obtained by making a sandwich of wire patterns of drawings A and B in perpendicular juxtaposition plus another insulation layer adjacent to exposed wire pattern and punching openings 16. Magnetic films 18 on insulation substrate 20 of drawing D are placed on top and bottom of the composite sandwich of drawing C. At each opening 16, the magnetic films from top and bottom are welded together to provide magnetic toroids at each crossover of wires 10 and 12. By punching out the center portion of each weld or using a weld pattern consisting of an annular ring, a compact structure and desirable magnetic characteristics are obtained.

Batch Fabrication of Magnetic Toroid Array

Wire patterns 10 and 12 of drawings A and B are established as sense or drive lines on insulation 11 and 13, respectively. A composite of intersecting wires is shown in drawing C. Such is obtained by making a sandwich of wire patterns of drawings A and B in perpendicular juxtaposition plus another insulation layer adjacent to exposed wire pattern and punching openings 16. Magnetic films 18 on insulation substrate 20 of drawing D are placed on top and bottom of the composite sandwich of drawing C. At each opening 16, the magnetic films from top and bottom are welded together to provide magnetic toroids at each crossover of wires 10 and 12. By punching out the center portion of each weld or using a weld pattern consisting of an annular ring, a compact structure and desirable magnetic characteristics are obtained.

The magnetic film pattern 18 can also consist of sections unconnected at the centers of openings 16. The sandwich of wire patterns in drawing C can include an additional wire pattern for use as a separate sense line leaving the other two patterns in drawings A and B to be used as selection drive lines.
