Video tape recorder for recording and reproducing two-channel component
signals of a video signal on a magnetic tape using two pair of heads
and alternately delayed signals
摘要:
A video tape recorder for recording two-channel component signals of a video signal on a magnetic tape and for reproducing the recorded signals includes a recording signal processing system for processing the two-channel component signals into first and second recordable signals, an electromagnetic conversion system including two pairs of magnetic heads for recording the first and second recordable signals, respectively, on the magnetic tape and for reproducing the first and second recorded signals, respectively, and a reproduced signal processing system for processing the reproduced signals into representations of the original two-channel component signals. Each pair of heads of the two pairs of heads are disposed so as to be apart by 180.degree. from each other on a rotary cylinder and so as to be apart by 90.degree. from each head of the other pair of heads.
