Device for record and reproduction of frequency-modulated signals includes voltage adder, generator of support frequency, frequency modulator, record amplifier, amplifier-restrictor, frequency detector, low frequency filters and band filter, frequency multiplier, delay element, analog-digital transformer, buffer collector. To increase accuracy of result of reproduction sue to decrease of time distortions there are included correction low frequency filter through which output of the first low frequency filter is connected to input of delay line and correction low frequency filter included between the input of information signal and the first input of voltage adder.
