Magnetic video recording device

Claim 1

IMAGE RECORDING MEANS COMPRISING A MAGNETIC SHEET RECORD MEDIUM HAVING S SURFACE FOR RECEIVING AN IMAGE RECORDING, A MAGNETIC HEAD COMPRISING A PAIR OF CONFRONTING MAGNETIC POLES WITH A GAP THEREBETWEEN FOR COUPLING TO SUCCESSIVE REGIONS OF THE SURFACE OF SAID RECORD MEDIUM, SAID HEAD HAVING SIGNAL FLUX PATHS OF SUCCESSIVELY DIFFERENT RELUCTANCE LINKING SUCCESSIVE CONFRONTING PORTIONS OF SAID MAGNETIC POLES WITH SUCCESSIVELY OFFSET PORTIONS OF A REGION OF THE SURFACE OF SAID RECORD MEDIUM WITH WHICH SAID HEAD IS COUPLED, ELECTRIC CIRCUIT MEANS COUPLED, OF SAID HEAD FOR EXERTING A SIGNAL MAGNETOMOTIVE FORCE THEREON PRODUCING MAGNETIC FIELDS AT THE SURFACE OF THE RECORD MEDIUM OF EFFECTIVE AMPLITUDE TO BE RECORDED THEREON OVER A PROPORTION OF THE EXTENT OF SAID CONFRONTING POLES AND OVER A PROPORTION OF SAID REGION OF SAID RECORD MEDIUM SURFACE WHICH IS A FUNCTION OF THE AMPLITUDE OF CURRENT FLOW IN SAID ELECTRIC CIRCUIT MEANS, MEANS FOR RECEIVING AN IMAGE SIGNAL VARYING IN ACCORDANCE WITH AN IMAGE TO BE RECORDED ON SAID RECORD MEDIUM AND COUPLED TO SAID ELECTRIC CIRCUIT MEANS FOR SUPPLYING ELECTRIC CURRENT PULSES TO SAID ELECTRIC CIRCUIT MEANS DURING COUPLING OF THE HEAD TO RESPECTIVE REGIONS OF THE RECORD MEDIUM SURFACE VARYING IN AMPLITUDE IN ACCORDANCE WITH THE IMAGE SIGNAL TO BE RECORDED, MEANS FOR RELATIVELY MOVING SAID HEAD INTO COUPLING RELATION TO THE SUCCESSIVE REGIONS OF THE SURFACE OF THE RECORD MEDIUM WHICH FORM AN AREA ARRAY COVERING THE EFFECTIVE AREA OF THE RECORD MEDIUM SURFACE, AND MEAND FDOR MAINTAINING THE HEAD AT SUBSTANTIALLY A CONSTANT POSITION WITH RESPECT TO A DIRECTION NORMAL TO THE SURFACE OF THE RECORD MEDIUM DURING RECORDING RECORDING OF AN IMAGE ON THE RECORD MEDIUM.
