Abstract
PURPOSE: To make easy the circuit constitution and its circuit control required for data processing, by recording another digital signal on another track, based on a clock signal picked up from a digital data on a recorded track.
CONSTITUTION: A reference clock generating circuit 3 outputs a clock signal S1 of predetermined frequency to a clock switching circuit 4. In this switching circuit 4, based on the reference signal in a playback data detection circuit 5, a clock signal is fed to a recording circuit 2. On the other hand, at the playback data detection circuit 5, for example, by detecting the frame synchronizing signal in playback data, whether or not the data is reproduced is discriminated, and if no data is reproduced in the switching circuit 4, the 1st clock signal S1 is fed to the recording circuit 2 and if reproduced, the 2nd clock signal S2 is fed to the circuit 2. Thus, the circuit constitution and the circuit control required for playback data processing can remarkably be simplified.
