Binary recording system

Claim 1

A NON-RETURN-TO-ZERO SYSTEM OF MAGNETIC RECORDING AND REPRODUCING COMPRISING A SOURCE OF A TRAIN OF CLOCK PULSES INCLUDING SEPARATED GROUPS OF N EQUALLY SPACED PULSES, A SOURCE OF TIMING PULSES EACH DELAYED RELATIVE TO A CORRESPONDING CLOCK PULSE, A SOURCE OF SERIAL BINARY INFORMATION SIGNALS WHEREIN EACH CHARACTER INCLUDES N BITS EACH REPRESENTING A "1" OR A "0", A MAGNETIC RECORDING AND REPRODUCING TRANSDUCER, GATING MEANS UNDER THE CONTROL OF SAID PULSES AND OPERATIVE TO SUPPLY CURRENT TO SAID TRANSDUCER WHICH REVERSES IN DIRECTION WITH EACH SUCCESSIVE CLOCK PULSE AND COINCIDENCE OF A TIMING PULSE AND SOLELY A "1" INFORMATION SIGNAL, WHEREBY THE TIMES OF SAID CURRENT REVERSALS ARE RECORDED AS A DISCONTINUITY ON A RECORDING MEDIUM, MEANS COUPLED TO SAID TRANSDUCER WHEN REPRODUCING THE RECORDED INFORMATION TO DETECT SAID DISCONTINUITIES REGARDLESS OF POLARITY AND GENERATE PULSES CORRESPONDING THERETO, A GAP DETECTOR MEANS TO SENSE THE GAP BETWEEN GROUPS OF PULSES, WHEREBY THE NEXT FOLLOWING PULSE REPRESENTS A CLOCK PULSE AND THE PUSLES BETWEEN CLOCK PULSES EACH REPRESENT A RECORDED "1", AND MEANS UNDER THE CONTROL OF SAID CLOCK PULSES AND SAID GAP DETECTOR FOR GATING EACH PULSES REPRESENTING A "1" AND THE ABSENCE OF A PULSE REPRESENTING "0" TO AN OUTPUT LINE.
