  • Patent number: 5057934
    Abstract: The invention provides a FM signal transfer-recording system of VTR including; a RF output signal through the low pass filter of the reproduction set is applied to the pre-amp through the high frequency compensation part of the record set, and a synchronization signal separated at the synchronization-separating part of the reproduction set generates a switching pulse of 30 Hz through 1 switch, horizontal synchronization-separating part and monostable multivibrator of the record set in order to synchronize control pulse part and the drum servo. Recording directly the reproduced RF signal without FM demodulation and modulation and applying the synchronization signal of the reproduction set to the record set so as to synchronize control pulse and the drum servo with the synchronization signal of the reproduction set may be possible and removing the screen blazing generated due to FM demodulation and modulation may be attained according to the present invention.
