る。In the same figure, 1 is a disk that contains, for example, a digital audio signal obtained by digital pulse modulation of the A-D signal, and additional information such as ``listening to the reproduced sound of the audio A signal.'' The image signal is digitally pulse modulated and the digital video signal -C is frequency modulated and then recorded as a series of intermittent pits on the same track. The signal recorded on the disk 1 is picked up and reproduced by the pink-up circuit 2 as a known light intensity change or electrostatic change, and is reproduced by the FM demodulator 3 as an FM signal.
After being demodulated, the signal is supplied to the decoder 4 and subjected to MFM decoding.

A shift means for shifting and extracting the code and synchronization signal with a clock pulse of a predetermined frequency, and detecting the synchronization signal 8 taken out from the shift means and corresponding to each I [each] - code, and corresponding to each synchronization signal. ”-the code is within one block]-
The data acquisition means outputs one pulse at an arbitrary frequency lower than the frequency of the cock pulse, and captures the C data into this arbitrary tarok pulse. Each code taken into the means is retrieved. This code output period consists of a control means for prohibiting each code from the means from being taken into the data holder. For example, the program ``Multiple'' such as ``event'', ``imcode'' and ``chapter'' indicating the recording position.
- codes can be output simultaneously without special commands from the control circuit, programming of the control circuit is easy, and new codes can be continuously retrieved using arbitrary clock pulses, thereby allowing random access. When doing so, you need to know exactly the recording position of the desired program.
Get the right features such as display and get accurate performance.
