Abstract :
The two-channel three-segment recording method previously developed for high-definition TV (HDTV) baseband VCR recording is considered. The following aspects of this recording method are investigated: the determination of appropriate FM allocation that matches the characteristics of the tape-head system, the use of rotary head amplifiers and a cosine equalizer, and the correction of characteristic differences between the two channels. A signal-to-noise ratio of over 40 dB has been achieved, and the jitter and moire are imperceptible
