A Thin Magnetic Film Shift Register

Abstract

An initial application of the dynamics and interactions of domains within continuous magnetic thin film structures is made to a shift register in which binary information is stored and translated in and along a continuous evaporated thin magnetic film. These thin magnetic film shift registers are capable of storing information having a density of several hundred bits per square inch of vacuum evaporated structure and of translating this amount of information at bit rates in excess of a megacycle with powers of less than 10 watts.
