PURPOSE:To prevent the generation of moire by forming one track pitch for an FM sound signal with an exclusive rotary head and recording a video track superimposed on the recorded track. CONSTITUTION:Video signal recording and reproducing rotary heads H1, H2 are fitted on a rotary drum 1 respectively in the interval of 180 deg.. Sound signal recording and reproducing rotary heads HA1, HA2 are fitted to a position in preceding by an angle theta to the rotary heads H1, H2. The video track recorded by the rotary heads H1, H2 and the sound track formed by the rotary heads HA1, HA2 are recorded on the same position. Thus, the mutual interference due to beat between carrier frequencies is reduced. |
