ABSTRACT:
An EIAJ-2, video tape recorder and reproducer machine having broadcast quality response characteristics achieved through the use of a wide band direct type FM modulator for encoding a video signal for recording onto a video tape, a pair of record/playback heads carried by a rotating drum which is partially wrapped by a length of the video tape which is transported past the drum such that the heads scan the tape in helical fashion, the speed of the drum being such that each head records upon a respective track of the video tape a segment of the modulated video signal which correspond to 1/3 of a field of the video signal, an FM demodulator for decoding the frequency modulated video signal which is recovered during playback, circuits for synchronizing the speed of the drum with the synchronization pulses of the video signal and for controlling the speed with which the tape is transported pass the drum and circuitry for minimizing distortion of the video signal caused when the segmented portions of the video signal are spliced together.
