ABSTRACT:
In a digital video signal recording apparatus of the kind arranged to output a coded signal with its length per picture arranged to be variable by compressing the amount of information of the digital video signal and to record the coded signal while forming many tracks in parallel on a tape-shaped recording medium, a compression ratio is adjusted in such a way as to make the coded signal corresponding to m pictures (m: an integer of 2 or more) have an amount of information recordable in n tracks (n: an integer of 1 or more).
