ABSTRACT:
A video signal recording/reproducing apparatus for recording/reproducing a high resolution video signal wherein the video resolution is enhanced by shifting a carrier frequency to a higher band in frequency modulation in a VCR's video signal recording mode, and by differently setting the frequency characteristics depending on the presence of a color signal in the video signal. The video signal recording/reproducing apparatus results in a highly enhanced resolution of a recording/reproducing video signal by determining use of a color signal trap in an equalizing block and a filter frequency for separating a luminance signal depending on the presence of a color signal in recording/reproducing a video signal after determining whether the color signal is present. Also, the video signal recording/reproducing apparatus results in a highly improved resolution of a recording/reproducing video signal by shifting an FM modulation carrier frequency to a higher band and by shifting a peaking frequency in an equalizing block to a higher band.
