A video signal recording device is provided with a time base extension of N-times to an input video signal to form a record 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 of each channel by 1/N horizontal scanning period. The video signal reproduction device makes a sync separated signal of each channel coincide with a horizontal synchronizing signal of the input video signal. More specifically, the reproduction device includes an OR circuit which conducts logical "Add" of the sync separated signals of the respective signals. Thereby the Sync separated signal obtained by the logical "Add" coincides with the horizontal Synchronizing signal of the input video signal.
