ABSTRACT:
A video signal recording and reproducing apparatus in accordance with the present invention includes A/D converters, a shuffling circuit and magnetic heads. The A/D converters A/D-convert a luminance signal Y and color difference signals P.sub.B and P.sub.R included in a video signal. The shuffling circuit divides each A/D converted data into first and second channels and further divides the first and second channels into data of a first segment including the color difference signal P.sub.R and data of a second segment including the color difference signal P.sub.B. The data of the first segments of the first and second channels are recorded on a magnetic tape with a spacing of one track by the magnetic heads, data of the second segment of the first channel is recorded by the magnetic head on a portion between the tracks where the first segments are recorded, and data of the second segment of the second channel is recorded on a portion adjacent to the track where the first segment of the second channel is recorded. In a hi-vision VTR, it is possible to prevent an image of improper or poor hues due to differences in characteristics between the channels and enhance a capability of dropout compensation.
