APPARATUS FOR PRODUCING A MAGNETIC RETURN STRUCTURE

摘要

A magnetic return structure having a system of control lines for use in a magnetic storer and apparatus for producing the same. A parallel series of conductors are applied to both sides of a foil of insulating material and a keeper composition is applied to the exposed foil and conductors in a manner that eliminates any air gaps therebetween without producing undesirable mechanical disruptions of the system.
