This is about the multi-channel recording method and its device recording two programs at one video tape. The device comprises a low pass filter and an 1H delay circuit (2) generating the PLL and a synchronization discernable circuit for synchronizing video signal source and Ch1, Ch2, a Y/C discernable circuit (6) including adders (4)(4'), a band pass filter, a time delay circuit at low band output (7'), a frequency transformer having the horizontal synchronization generating signal and reference signal oscillator (10) and a low band modulation circuit (15).
