Abstract

PURPOSE: To eliminate the effect of jitter, by carrying out the recording with an addition of the sampling pulse of the frequency adjacent to the upper limit of the video signal frequency band which is required during the recording.
CONSTITUTION: The sampling pulse applied to the terminal 6 is supplied to the PLL circuit 7 and converted into the 10-fold frequency to be furthermore divided down to the frequency of 1/16 through the frequency divider 12. The sampling pulse thus produced is turned into the frequency adjacent to the upper limit of the frequency band necessary for the video signal 1 and then receives an FM modulation after an addition at the adder 4. In reproduction, the FM signal detected through the photoelectric transducer 14 is demodulated by the demodulator 17, and then the sampling pulse is extracted through the tuning circuit 19 via the PLL circuit 20 and the frequency dividing circuit 25. In other words, both the reproduced video signal and the sampling pulse were recorded at one time, and thus the reproduced video signal is sampled by the reproduced sampling pulse. In this way, the jitter during the reproduction can be eliminated.
