Abstract

PURPOSE: To enhance the effect of correction, by adding FM data signal and reference signal, and by recording and reproduction the summed up signal with one signal track.
CONSTITUTION: The FM modulation signal c in FM modulating 2 the data input signal a together with the carrier b, and the reference signal d of the reference signal oscillator 4 are inputted to the adder 11 to produce the sum signal j, which is recorded on the data track 51. The recording signal is picked up with the reproducing unit 6, this is separated into the data signal l' and reference signal m' with BPF 12 and 13 to obtain the data demodulation signal g' and reference demodulation signal h' from the FM demodulators 7 and 8 and also to otbain the correction data i' from the terminal 10 with the input of the both to the differential amplifier 9. Thus, the reference signal and data signal detecting harmful components are recorded on the same point of tape, allowing to obtain remarkably high accuracy for the corrective effect.
