Abstract

PURPOSE: To obtain the recorder and reproducer with good video quality, by decreasing the amount of mixing of the color signal in low band conversion depending on the recording position of disc to the luminance component in FM modulation much at inner circumference than at outer circumference.
CONSTITUTION: The color video signal entered to the input terminal 101 is separated into the luminance and chroma components at the filter circuit 102. The luminance component is fed to the processing circuit 103, where it is in FM comulation 104. The color signal is fed to the processing circuit 105, it is in low band conversion at the balance modulation circuit 106, and is fed to the color signal gain control circuit 107. Further, the luminance FM signal and the color signal in low band conversin are superimposed with the synthesis circuit 108, they are binary signal in the limiter circuit 109, and it is fed to the gate circuit 21. Moreover, the information of position detected at the position detection section 111 is converted 110 to DC voltage, and this voltage controls the gain of the color signal gain control circuit 107 so that the recording at the inner circumference is decreased than the recording at the outer circumference of disc.
