  • Patent number: 3964034
    Abstract: A method of operating and an apparatus comprising a very compact, bit-organized nondestructive readout (NDRO) random-access magnetic memory system is disclosed. The memory system is directed toward an improvement of the memory system of the D. S. Lo, et al., U.S. Pat. No. 3,550,101 and includes a continuous oligatomic ferromagnetic film (a film that is too thin to permit either Bloch walls or cross-tie walls, but does permit Neel walls) that has the property of uniaxial anisotropy which property provides an easy axis in the plane of the film along which the film's remanent magnetization may be aligned in either of two opposed information states and a hard axis in the plane of the film that is perpendicular to the easy axis.
