In a recorder system for recording a video signal, the video signal is modulated by a sine wave FM modulator and is then fed to a delay equalizer for successively rotating a phase of the modulated video signal so that a phase of high order side band components of the modulated video signal is shifted by 180 degrees relative to each other, and is then recorded on a video tape having a characteristic as a limiter. Hence, a moire component can be reduced. In a reproducing system, a reproduced video signal is fed to a filter circuit having a serially-connectred limiter and high-pass filter, a low-pass filter connected parallelly to the limiter, and an adder for adding an output signal of the high-pass filter and an output signal of the low-pass filter. A plurality of the filter circuits are serially connected so that the signal-to-noise ratio (S/N ratio) can be improved.
