Abstract
Abstract A magnetic memory device has a number of substantially parallel elongated memory elements arranged within a plane and extending transverse to and magnetically coupled with a group of conductors parallel to the plane. The conductors are disposed on a dielectric sheet spaced from the memory elements. A soft layer of magnetic material covers one side of the dielectric sheet. On the opposite side of the dielectric sheet, strips of soft magnetic material are disposed between the conductors. This side of the dielectric sheet is secured to the plane of memory elements.

Claim 1
Independent Claim
154 words
A plated wire memory plane, having magnetic coated conductive wires as memory elements and spaced conductive word straps which generate magnetic fields for storage and retrival of information in the memory elements, comprising the improvements of A. a dielectric sheet 1. having first and second surfaces 2. disposed between said memory elements and said spaced conductive straps, and 3. defining with its first surface opposite the memory element a reference surface to which said conductive straps are secured, B. a maGnetic keeper which covers the exposed surfaces of said conductive straps and extends between said straps, C. strips of soft magnetic material 1. of a high permeability 2. disposed on the second surface of said dielectric sheet opposite only the spaces between the conductive straps, and 3. contiguous with said memory elements such that closed, lowreluctance paths are developed around each of said word straps and through the magnetic coating of the memory elements.
