Abstract
PURPOSE: To ensure the control such as time correction, by reproduction of control signal in high level through de-emphasis of only high band at reproduction and through pre-emphasis of control signal at recording together with high band of main signal, by setting the control signal included in the main signal to low band.
CONSTITUTION: The main signal from the converter 1 and the control signal such as time axis correction from the control signal generating unit 2 are given to the pre- emphasis circuit 3, pre-emphasis is made to the control signal set low band together with the high band of the main signal, FM signal is made from the FM modulation curcuit 4, and recording is made via the amplifier 5 at the recorder 6. The reproducing signal from the recorder 6 is amplified at the amplifier 7 and it is given to the de-emphasis circuit 9 via the FM demodulation circuit 8 and only high band is de- emphasized and given to the time axis correction circuit 10. The control signal at low band is outputted as high level. Accordingly, the discrimination of the control signal is made easy from other signals to achieve good S/N, and the time axis correction at the correction circuit 10 is ensured.
