Pattern sensitivity compensation in high pulse density recording

Claim 1

THE IMPROVEMENT OF PULSE DATA PROCESSING APPARATUS FOR RECORDING BINARY DIGIT PULSES COMPRISING A RECORD MEDIUM UPON WHICH BINARY DIGIT PULSES ARE TO BE RECORDED, A SOURCE OF ELECTRICAL SIGNALS REPRESENTATIVE OF THE BINARY DIGIT PULSES TO BE RECORDED, A SOURCE OF TIMING PULSES HAVING AN OUTPUT OF IN-PHASE TIMING PULSES, ADVANCED TIMING PULSES AND DELAYED TIMING PULSES, LOGIC SENSING MEANS ADAPTED TO RECEIVE SAID BINARY DIGIT PULSES AND SAID TIMING PULSES, MEANS FOR SIMULTANEOUSLY APPLYING A GROUP OF SAID BINARY DIGIT PULSES FROM SAID SOURCE TO SAID LOGIC SENSING MEANS, SAID GROUP BEING COMPRISED OF A BINARY DIGIT PULSE, ITS IMMEDIATELY PRECEDING BINARY DIGIT PULSE AND ITS IMMEDIATELY SUCCEEDING BINARY DIGIT PULSE, MEANS FOR SIMULTANEOUSLY APPLYING SAID IN-PHASE TIMING PULSES SAID ADVANCED TIMING PULSES AND SAID DELAYED TIMING PULSES TO SAID LOGIC SENSING MEANS AT THE SAME TIME SAID GROUP OF BINARY DIGIT PULSES IS APPLIED TO SAID LOGIC SENSING MEANS, AND RECORDING CONTROL MEANS CONNECTED TO THE OUTPUT OF SAID LOGIC SENSING MEANS TO RECORD EACH OF THE SENSED BINARY DIGIT PULSES UPON SAID RECORD MEDIUM IN SYNCHRONISM WITH SAID IN-PHASE TIMING PULSES, SAID ADVANCED TIMING PULSES, OR SAID DELAYED TIMING PULSES AS DETERMINED BY THE OUTPUT OF SAID LOGIC SENSING MEANS.
