A video signal recording-reproduction device is provided with a recording device for applying time base extension of N-times to an input video signal to form a recording signal and recording the signal on a recording medium by dividing it into a plurality of channels the number of which is given by N or integral multiples of N. The recording device includes a line memory control circuit for shifting a phase of a signal such that the phase shift between adjacent channels is a 1/N horizontal scanning period. The video signal recording-reproduction device is also provided with a reproduction device for forming an output video signal by reproducing a recording signal from each channel and by making a separated sync signal of the recording signal of each channel to coincide with a horizontal synchronizing signal of the input video signal. More specifically, the reproduction device includes an OR circuit which conducts a logical OR operation upon the separated sync signals of the respective signals, each reproduced from each channel. Thereby, the separated sync signal obtained by the logical OR operation coincides with the horizontal synchronizing signal of the input video signal.
