ABSTRACT:
A cylindrical domain memory has a storage medium constructed in layer form which is provided with cylindrical domains which are magnetized at right angles to the layer plane, the magnetization being directed opposite to the magnetization of the surrounding material and to that of the magnetic bias field. A propagation structure has an overlay pattern of individual elements of magnetizable material applied in the form of layers to the one layer plane and a rotary magnetic field is directed parallel to the layer plane, which field causes displacement of the cylindrical domains along a path determined by the propagation structure. The propagation structure comprises L-shaped individual elements which are staggered in stepped fashion relative to one another.
