| titleOfInvention | Magneto-optical cylindrical magnetic domain memory |
| abstract | 1. A MAGNETO-OPTICAL SIGNAL TRANSLATING DEVICE FOR BINARY DIGITAL SIGNALS COMPRISING: A. FIRST AND SECOND OPTICALLY TRANSLUCENT UNIAXIALLY ANISOTROPIC FERROMAGNETIC CRYSTAL PLATELETS OF EQUAL THICKNESS, ONE OF THE MAJOR PLANE SURFACES OF EACH OF SAID PLATELETS BEING JUXTAPOSED IN LIGHT TRANSMITTING RELATIONSHIP TO A MAJOR PLANE SURFACE OF THE OTHER OF SAID PLATELETS, AND EACH OF SAID PLATELETS HAVING AN EASY AXIAL OF MAGNETIZATION PERPENDICULAR TO THE PLANE OF SAID MAJOR SURFACE OF SAID PLATELET; B. MEANS FOR MAGNETICALLY BIAS SAID FIRST AND SECOND PLATELETS RESPECTIVELY IN OPPOSING POLARITIES ALONG SAID EASY AXES TO MAGNETIZATION SO THAT THEIR RESPECTIVE FARADAY ROTATIONALS WILL NORMALLY COMPENSATE EACH OTHER; C. MEANS TO TRANSILLUMINATE AND OPTICALLY SUPERIMPOSES IN REGISTRTION SAID PAIR OF PLATELETS WITH A BEAM OF POLARIZED LIGHT; D. MEANS TO ESTABLISH AT LEAST ONE MOVABLE CYLINDRICL MAGNETIC DOMAIN IN SAID FIRST PLATELET HAVING A MAGNETIC POLARITY ANTIPARALLEL TO THE DIRECTION OF SAID MAGNETIC BIAS FOR SAID FIRST PLATELET AND MEANS TO ESTABLISH AT LEAST CYLINDRICAL MAGNETIC DOMAIN IN SAID SECOND PLATELET HAVING A MAGNETIC POLARITY ANTIPARALLEL TO THE DIRECTION OF SAID MAGNETIC BIAS FOR SAID SECOND PLATELET, SAID MAGNETIC DOMAINS RESPECTIVELY REPRESENTING THE BINARY VALUE OF ONE BIT OF A DIGITAL SIGNAL AND OF ONE BIT OF A DIGITAL REFERENCE TO WHICH SAID DIGITAL SIGNAL IS SUBSTRACTIVELY COMPARED; E. POLRAIZED ANALYZER MEANS POSITIONED TO RECEIVE LIGHT TRANSMITTED THROUGH SAID PAIR OF PLATELEST TO DETECT ANY UNCOMPENSATED CHANGE IN THE STATE TO POLARIZED OF SAID LIGHT PRODUCED BY ITS TRANSMISSION THROUGH SAID PLATELETS; AND F. LIGHT TRANSDUCING MEANS POSITIONED TO RECEIVE LIGHT TRANSMITTED THROUGH SAID POLARIZATION ANALYZER TO PRODUCE AN OUTPUT INDICATIVE OF SAID DETECTED UNCOMPENSATED CHANGE IN THE STATE OF POLRAIZATION. |
