PURPOSE:To record effectively a wide frequency band video signal by dividing a luminance signal into signals of plural channels for dot-interlacing, recording said signals in each multi-track channel formed sequentially on a recording medium and recording a chrominance information signal on at least one channel of each track. CONSTITUTION:Luminance signals separated by a separator circuit 13 is divided into signals of two channels which dot-interlace by means of a multiplexer 17, and supplied to filters 18a and 18b. The filters 18a and 18b include a comb- shaped filter for removing and LPF and folded noise. The luminance signals of each channel have unnecessary signals removed by the filters 18a and 18b, are FM modulated with the aid of FM modulator circuits 19a and 19b, added to a low frequency conversion macro signal by mixers 16a and 16b, and then recorded in heads 21a and 21b through amplifiers 20a and 20b. The head 21a corresponds to heads 1a and 2a, and the head 21b corresponds to heads 1b and 2b, respectively. |
