Abstract
PURPOSE: To reduce waveform distortion to improve S/N by setting a reverse resonance write circuit and a head resonance read circuit and offsetting the phase characteristics between the write circuit and read circuit.
CONSTITUTION: The device to carry out frequency modulation (FM) of a video signal, record the modulated signal by means of writing it in magnetic medium 11 and regenerate the recorded signal by means of reading it is improved. When the modulated signal is recorded by write head 12, reverse resonance write circuit 4 is attached in order to supply a write current, which supply reverse resonance frequency characteristics having reverse resonance frequency to the surroundings of the carrier frequency of modulated signal, to write head 12. When the modulated signal is read out by read head 13, frequency characteristics of the amplitude and phase of head resonance read circuit 5 are offset by the amplitude and phase characteristics of write circuit 4 with reverse resonance characteristics, so that the evenness of frequency-to-amplitude characteristics and the linearity of phase characteristics are maintained by head resonance read circuit 5.
