Claim 1

A MAGNETIC SYSTEM COMPRISING A MOUNTING FRAME HAVING AN ENCLOSURE THEREIN WITH AN EXTERNAL OPENING, A STORAGE RECORD INCLUDING A STRUCTURE OF A CONDUCTIVE MATERIAL HAVING NONMAGNETIC PROPERTIES AND A MAGNETIC WIRE HAVING FIRST AND SECOND ENDS, SAID MAGNETIC WIRE MOUNTED AROUND AND MAINTAINED IN DIRECT CONTACT WITH SAID STRUCTURE, SAID MAGNETIC WIRE MAINTAINED UNDER TENSION TO PROVIDE MAGNETIC WIRE MAINTAINED UNDER TENAXIS THEREOF, SAID WIRE UNDER TENSION HAVING A RELAXING RECTANGULAR HYSTERESIS CHARACTERISTIC SUCH THAT A SUBSTANTIALLY GREATER MAGNETOMOTIVE FORCE IS REQUIRED TO ESTABLISH A MAGNETIC DOMAIN WALL THAN IS REQUIRED TO PROPAGATE THE MAGNETIC DOMAIN WALL ALONG SAID WIRE, SAID STORAGE RECORD HAVING DIMENSIONS FOR BEING REMOVABLY POSITIONED IN SAID ENCLOSURE, READ-IN MEANS MOUNTED ON SAID FRAME AND MAGNETICALLY COUPLED TO THE FIRST END OF SAID WIRE FOR ESTABLISHING DOMAINS THEREIN HAVING A MAGNETIC ORIENTATION OF A FIRST OR A SECOND DIRECTION, A PROPAGATING WINDING MOUNTED TO SAID FRAME AND MAGNETICALLY COUPLED TO SAID WIRE TO SHIFT THE POSITION OF SAID DOMAINS IN PREDETERMINED STEPS ALONG SAID WIRE, A SOURCE OF READ-IN PULSES COUPLED TO SAID READ-IN MEANS FOR FORMING DOMAINS WITH A MAGNETIC ORIENTATION IN SAID FIRST DIRECTION DURING FIRST ALTERNATE PERIODS AND WITH A MAGNETIC ORIENTATION SELECTED IN SAID FIRST OR A SECOND DIRECTION DURING SECOND ALTERNATE PERIODS ADJACENT TO SAID FIRST ALTERNATE PERIODS, A SOURCE OF PROPAGATING PULSES COUPLED TO SAID PROPAGATING WINDING FOR APPLYING SIGNALS TO PROPAGATE SAID DOMAINS ALONG SAID MAGNETIC WIRE IN SAID PREDETERMINED STEPS, AND READ-OUT MEANS MOUNTED ON SAID FRAME AND MAGNETICALLY COUPLED TO THE SECOND END OF SAID MAGNETIC WIRE TO DEVELOP INFORMATION SIGNALS IN RESPONSE TO DOMAINS MOVING THEREBY.
