  • Patent number: 5200862
    Abstract: A device capable of reproducing recording information without error and which eliminates a deterioration in a reproduced image quality during a dubbing operation. The still image reproducing device has a change-over switch that is capable of selectively delivering a demodulated image signal obtained through delaying an image signal by a time corresponding to 0.5 H. A control circuit outputs a switching control signal upon completion of one full rotation of a recording medium. A decoder decodes the demodulated recording information in response to a decoder control circuit, enabling the decoder to operate when the change-over switch is delivering the demodulated composite image signal. In the still image recording device, the composite image signal is FM demodulated. The demodulated composite image signal is multiplexed with a signal obtained by encoding and modulating the recording information. The multiplexed signal is supplied to a recording head through the gate circuit.
