    摘要: A pair of recording heads are mounted on a rotary cylinder for recording a video signal in slanted tracks on magnetic tape. The recording heads are mounted in a common plane and each has a different azimuthal angle. A pair of reading heads are mounted on the same rotary cylinder for reading the video signal recorded on the magnetic tape. The reading heads are mounted in a plane offset from the plane of the recording heads and have azimuthal angles that match the azimuthal angles of the recording heads. A mixing circuit mixes a component of the video signal ready from the magnetic tape by one of the recording heads with a video signal from a video signal source to generate a mixed video signal. The mixed video signal is returned to one of the recording heads for recordation on the magnetic tape.
