Abstract: THE DISCLOSURE DESCRIBES AN IMPROVED FORM OF REENTRANT MAGNETIC WIRE FOR USE IN MAGNETIC STORAGE DEVICES SUCH AS DOMAIN WALL SHIFT REGISTERS. THE IMPROVEMENT IS OBTAINED BY REDUCING THE NONUNIFORMITIES IN THE MAGNETIC CHARACTERISTICS OF THE WIRE (FOUND TO BE CAUSED BY THE SURFACE DEFECTS) BY COATING THE WIRE WITH A THIN FILM OF THE SAME OR A SIMILAR MAGNETIC MATERIAL.
