摘要

A color video signal recording and reproducing system includes a recording system which comprises first head gaps mounted on a rotary body, second head gaps mounted on the rotary body at locations lagging each of the first head gaps by a predetermined distance along a rotating direction of the rotary body, and a recorder for recording signals onto a tape which is caused to travel in a state where the tape is wrapped around a peripheral surface of the rotary body. The recorder first records a low-band converted carrier chrominance signal onto a first track by one of the first head gaps, and thereafter records a frequency modulated luminance signal onto a second track by one of the second head gaps. The second track has a track width which is larger than a track width of the first track and is formed over the first track in an overlapping manner with a track pitch which is at least larger than the track width of the first track. A reproducing system comprises a circuit for separating the low-band converted carrier chrominance signal from a signal which is reproduced from the tape by the first or second head gaps, and a circuit for separating the frequency modulated luminance signal from a signal which is reproduced from the tape by the second head gaps.
