Claims

1. A REDUNDANT MAGNETIC STORAGE SYSTEM FOR STORING BINARY INFORMATION BITS HAVING AT LEAST ONE STORAGE PLANE, SAID SYSTEM COMPRISING:

FIRST, SECOND, THIRD AND FOURTH REDUNDANT ARRAYS OF MAGNETIC CORE ELEMENTS IN SAID PLANE, EACH OF SAID ARRAYS HAVING CORRESPONDING SIMILAR ROW AND COLUMN COORDINATE LOCATIONS, SAID CORE ELEMENTS BEING FURTHER ARRANGED IN REDUNDANT SETS, EACH OF SAID SETS INCLUDING A MUTUALLY EXCLUSIVE CORE ELEMENT FROM EACH OF THE FOUR ARRAYS, THE CORE ELEMENTS INCLUDED IN A RESPECTIVE SET BEING LOCATED AT THE SAME COORDINATE LOCATIONS IN EACH OF THEIR RESPECTIVE ARRAYS, AND EACH OF SAID CORE ELEMENTS BEING SETTABLE TO EITHER OF TWO MAGNETIC STATES RESPECTING THE BINARY INFORMATION BITS "1" AND "0," RESPECTIVELY;

COINCIDENT-CURRENT SELECTION MEANS FOR REDUNDANTLY SETTING THE RESPECTIVE CORE ELEMENTS IN EACH OF THE PARTICULAR SETS TO THE SAME MAGNETIC STATE OF SAID EITHER OF TWO MAGNETIC STATES, EACH PARTICULAR SET OF CORE ELEMENTS BEING SET BY SAID SELECTION MEANS TO THE PREDETERMINED ONE OF SAID TWO MAGNETIC STATES WHICH REPRESENTS THE BINARY INFORMATION BIT TO BE STORED IN THE PARTICULAR SET, SAID COINCIDENT-CURRENT MEANS COMPRISING A PLURALITY OF HALF-CURRENT SELECT WINDINGS AND MUTUALLY EXCLUSIVE CURRENT DRIVERS COUPLED THERETO, EACH OF THE CORE ELEMENTS OF SAID FIRST AND SECOND ARRAYS LOCATED IN THE SAME COLUMN COORDINATE LOCATIONS BEING COMMONLY LINKED BY A MUTUALLY EXCLUSIVE ONE OF SAID PLURALITY OF HALFCURRENT SELECT WIDNINGS, EACH OF THE CORE ELEMENTS OF SAID THIRD AND FOURTH ARRAYS LOCATED IN THE SAME COLUMN COORDINATE LOCATIONS BEING COMMONLY LINKED BY A MUTUALLY EXCLUSIVE ONE OF SAID PLURALITY OF HALF-CURRENT SELECT WINDINGS, EACH OF THE CORE ELEMENTS OF SAID FIRST AND THIRD ARRAYS LOCATED IN THE SAME ROW COORDINATE LOCATIONS BEING COMMONLY LINKED BY A MUTUALLY EXCLUSIVE ONE OF SAID PLURALITY OF HALF-CURRENT SELECT WINDINGS, AND EACH OF THE CORE ELEMENTS OF SAID SECOND AND FOURTH ARRAYS LOCATED IN THE SAME ROW COORDINATE LOCATIONS BEING COMMONLY LINKED BY A MUTUALLY EXCLUSIVE ONE OF SAID HALFCURRENT SELECTE WINDINGS;

FIRST AND SECOND SENSE WINDINGS, EACH OF SAID CORE ELEMENTS OF SAID FIRST AND FOURTH ARRAYS BEING COMMONLY LINKED BY SAID FIRST SENSE WINDING, AND EACH OF SAID CORE ELEMENTS OF SAID SECOND AND THIRD ARRAYS BEING COMMONLY LINKED BY SAID SECOND SENSE WINDING;

AND OUTPUT MEANS FOR RECEIVING THE INDICATION OF SAID FIRST AND SECOND SENSE WINDINGS TO PROVIDE RESPECTIVE OUTPUT SIGNALS INDICATIVE OF THE PARTICULAR MAGNETIC STATES OF SAID SETS, SAID OUTPUT MEANS HAVING FIRST AND SECOND SENSE AMPLIFIERS AND OR CIRCUIT MEANS, SAID FIRST AND SECOND SENSE AMPLIFIERS HAVING FIRST AND SECOND INPUT TERMINALS COUPLED TO SAID FIRST AND SECOND SENSE WINDINGS, RESPECTIVELY, AND FURTHER HAVING FIRST AND SECOND OUTPUT TERMINALS, SAID OR CIRCUIT MEANS HAVING A PAIR OF THIRD AND FOURTH INPUT TERMINALS COUPLED TO SAID FIRST AND SECOND OUTPUT TERMINALS, RESPECTIVELY, AND SAID OR CIRCUIT MEANS HAVING AN OUTPUT TERMINAL AT WHICH SAID OUTPUT SIGNALS ARE PROVIDED.
