Abstract

PURPOSE:To facilitate the recording and reproducing of a new identification signal by synthesizing a bit of the identification signal with a complex synchronizing signal in its 1H correspondingly, modulating the synthesized signal in frequency (FM) and recording it to an optical disk. CONSTITUTION:In case of recording the new identification signal by the user, the identification data signal (n) inputted in advance to a system controller 20 and the complex synchronizing signal (l) of a reference signal generating circuit 10 are inputted into an identification signal generating circuit 100 to be synthesized. In this case, the data are recorded as per one bit rate corresponding to one horizontal scanning period (1H) of the complex synchronizing signal. This synthesized signal is modulated in frequency (FM) in a recording signal processing circuit 16 to be recorded to the disk 6. At the time of reproducing, the recorded signal (FM) is demodulated in a reproducing signal processing circuit 22 and then only the identification signal is shaped in its waveform by an identification signal reproducing circuit 200 to be transferred to a microcomputer. For this, a new identification signal can easily be recorded and reproduced without being influenced by a noise component.
