Nondestructive readout magnetic memory

Claim 1

A NONDESTRUCTIVE READOUT MAGNETIC MEMORY APPARATUS COMPRISING: A MAGNETIC CORE HAVING A CENTRAL APERTURE HAVING A SUBSTANTIALLY HIGH REMANENT-MAGNETIZATION FLUX PATH THEREABOUT FOR STORING BINARY INFORMATION IN SAID CORE AS A FUNCTION OF THE DIRECTION OF FLUX IN SAID PATH, AT LEAST ONE ADDITIONAL LEG OF SAID CORE HAVING A SUBSTANTIALLY NEGLIGIBLE REMANENT-MAGNETIZATION, SAID ADDITIONAL LEG PROJECTIONS FROM SAID CENTRAL APERTURE''S INTERNAL PERIPHERY ACROSS SAID CENTRAL APERTURE AND SEPARATED FROM AN OPPOSING PORTION OF SAID CORE BY AIR GAP, SAID LEG PROVIDING MAGNETIC COUPLING BETWEEN OPPOSING PORTIONS OF SAID CORE, WRITING MEANS MAGNETICALLY COUPLED TO SAID PATH AT ITS JUNCTURE WITH SAID LEG, SENSING MEANS MAGNETICALLY COUPLED TO SAID PATH IN SAID AIR GAP, INTERROGATE MEANS MAGNETICALLY COUPLED TO SAID LEG, FLUX INDUCED IN SAID LEG BY SAID INTERROGATE MEANS CAUSING A TEMPORARY ALTERATION OF THE FLUX OF SAID PATH ADJACENT SAID SENSING MEANS, SAID TEMPORARY ALTERATION OF THE FLUX OF SAID PATH ADJACEN SAID SENSING MEANS GENERATING AN OUTPUT SIGNAL IN SAID SENSING MEANS INDICATIVE OF THE BINARY INFORMATION STORED IN SAID CORE.
