Magnetic Film Memory

The magnetic film memory provides a substantially uniform galvanic connection between metallic base plate 10 and conductive carrier plate 12 for disturbance-free current conduction between them, by utilizing electrically conducting layers or foils 13.

Plate 12 of the arrangement at A supports a plurality of magnetic film storage cells 14 disposed on a layer of e. g., silicon oxide 16. Plate 12 is inserted into opening 18 in plate 10 from below. It is held in position by auxiliary plate 20 attached to plate 10 by screws 22.

Plate 12 has concave recesses 28 on each side which end in a shoulder-like extension 26 toward plate 10. The latter has corresponding concave recesses 28 and step-shaped cutout 30. Recesses 24 and 28 form cavities to receive an elastic, roller-shaped body 32, e. g., a hollow rubber cylinder. This has an outside diameter as large as, or even slightly larger than, the diameter of one of the cavities. Each layer or foil 13, which can be silver foils of 20 micron thickness and of a length equal to that of a side of plate 12, is disposed between one body 32 and both plates 10 and 12. Body 32 presses foil 13 against plates 10 and 12. Thus, a substantially uniform galvanic connection results approximately at the level of the upper surfaces of plates 10 and 12. Body 32 can be fixedly attached, as by gluing, to a suitable area 34 of recess 24 in plate 12.

The connection between plates 10 and 12 via foil 13 pressed to them by body 32...
