Abstract
A magnetic memory device in which information is stored in the form of strip domains in a layer of magnetic material supported by a layer of ferromagnetic material. The ferromagnetic material contains a pattern of alternately magnetized strips for sustaining a magnetic field periodically varying in a first coordinate direction and directed transverse to the domain layer. The device also includes a generator for receiving and converting data into configurations of the strip domains in the plate.
