[Embodiment of device]

 Hereinafter, with reference to the drawings, the present invention will be described in detail by way of examples. Referring to FIG. 1, an explanatory view of a circuit block diagram of the present invention is shown. As shown in the figure, in the "optical disc control device capable of synchronously reproducing and recording" of the present invention, the output control terminals of the central processing unit (CPU) 10 are respectively connected to the optical disc reproduction circuit 20 and the first data. The signal processor 30, the audio and video signal processor 40, the second data signal processor 50, and the optical disc recording circuit 60 are connected to the input terminals. In addition, the output and input terminal of the optical disc reproducing circuit 20 are connected to the output and input terminal of the first data signal processor 30, and the output of the optical disc recording circuit 60 and the input terminal of the second data signal processor 50 are connected. The input and output terminals of the first data signal processor 30 are connected to the output and input terminals of the second data signal processor 50. Further, the output and input terminals of the first and second data signal processors 30, 50 are connected to the output and input terminals of the audio and video signal processor 40, respectively. The output and input terminals of the audio and video signal processor 40 described above are connected to the input terminals of the speaker 70 and the monitor 80, respectively. As a result, a control device for an optical disc that can perform playback and recording in synchronization is configured.

When the optical disk reproducing circuit 20, the first data signal processor 30, the audio and video signal processor 40, the monitor 80, etc. are controlled by the central processing unit 10 described above, the audio from the optical disk reproducing circuit 20 is controlled. The video signal is processed by the first data signal processor 40, transferred to the audio and video signal processor 40, and broadcast from the speaker 70 and the monitor 80. On the other hand, when the central processing unit 10 controls the second data signal processor 50 and the optical disc recording circuit 60, the audio and video signals are transferred from the second data signal processor 50 to the optical disc recording circuit. , Finally recorded on an optical disc.

Incidentally, the second data signal processor 50 and the optical disk recording circuit described above have the same functions as the optical disc reproducing circuit and the first data signal processor, and can be applied to a CD stereo. However, the above description is merely an example of an ideal embodiment for explaining the present invention, and does not limit the present invention in any way. Therefore, in the same spirit as the present invention, any improvements and modifications are included in the protected area of the present invention.
