Thin film magnetic storage

Claim 1

IN A MAGNETIC DEVICE FOR STORAGE OF BINARY DATA; AN OPEN-CORE MAGNETIC ELEMENT HAVING A PREFERRED AXIS OF MAGNETIZATION AND BEING CAPABLE OF ASSUMING EITHER OF TWO STABLE STATES OF MAGNETIC REMANENCE ONE OF WHICH IS A REFERENCE STATE, AND FORMING A MAGNETIC CIRCUIT WHOSE RETURN PATH IS THROUGH SURROUNDING SPACE; A RESTORING CONDUCTOR HAVING A PORTION ORIENTED AT AN ACUTE ANGLE WITH RESPECT TO SAID PREFERRED AXIS OF MAGNETIZATION AND LOCATED IN INDUCTIVE COUPLING RELATION TO SAID MAGNETIC ELEMENT FOR PROVIDING IN RESPONSE TO CURRENT FLOW THROUGH SAID RESTORING CONDUCTOR A MAGNETIZING FIELD CAPABLE OF SWITCHING SAID MAGNETIC ELEMENT FROM ITS OTHER TO ITS REFERENCE STATE; AND A SENSE CONDUCTOR HAVING A PORTION ORIENTED WITH RESPECT TO SAID PREFERRED AXIS AT AN ANGLE WHICH IS THE COMPLEMENT OF SAID ACUTE ANGLE, SAID PORTION OF SAID SENSE CONDUCTOR BEING LOCATED IN INDUCTIVE COUPLING RELATION TO SAID MAGNETIC ELEMENT, WHEREBY A VOLTAGE IS INDUCED IN SAID SENSE CONDUCTOR IN RESPONSE TO THE SWITCHING OF SAID MAGNETIC ELEMENT FROM EITHER ONE TO THE OTHER OF ITS SAID STATES, SAID PORTION OF SAID SENSE CONDUCTOR BEING POSITIONED IN ORTHOGONAL RELATION WITH RESPECT TO SAID PORTION OF SAID RESTORING CONDUCTOR SO AS TO HAVE SUBSTANTIALLY ZERO AIR MUTUAL INDUCTIVE COUPLING THEREWITH, WHEREBY SUBSTANTILLY NO VOLTAGE IS INDUCED IN SAID SENSE WINDING IN RESPONSE SOLELY TO THE FLOW OF CURRENT THROUGH SAID RESTORING CONDUCTOR.
