PURPOSE:To form a digital reproducing device, by recording an analog video signal with a digital signal and a discriminating signal split into a plurality of channels and processing a reproducing signal line at each group of equal azimuth angle of a track. CONSTITUTION:Digital signals Sa... of each channel are reproduced at the same time from tracks 2A... with heads 1A... and adjacent azimuth angles for the heads 1A... and tracks 2A... are made different from each other, the recorded digial signals are attenuated for low frequency components through 8-10 bit conversion and crosstalk between tracks is less. A signal applied from a reproducing amplifier 31 to a reproducing processor is converted into a parallel signal, decoded to the original sample sets Sa..., this set is applied to a time base collector 33 to reject time axis fluctuation, and time division multiplex is made so that one set is alternate at the next multiplexer 34, and the set is shared to an essential channel with a channel discrimination signal at an interchanger 35 to obtain the original analog signal through error correction and the like.
