Reference numeral 13 is a microcomputer (hereinafter, referred to as a microcomputer) that controls the above system, and 14 is a key input unit.

The operation of the recording / reproducing apparatus configured as described above will be described below.

First, when playing a video CD, the video C of the video CD operating unit 14a in the key input unit 14 is reproduced.
When the D play button is pressed, the pickup 2 extracts the recorded information from the disc 1 under the control of the microcomputer 13, and switches the output switching SW 11 to the c side. The signal extracted by the pickup 2 is input to the video CD reproducing section 3, and the video CD reproducing section 3 converts the information into an analog audio signal and an analog video signal.
Then, the output terminal 12 is output via the output switching SW 11.

When the video tape is reproduced, when the VTR reproduction button of the VTR operation section 14b in the key input section 14 is pressed, the contents recorded on the video tape 10 are reproduced by the control of the microcomputer 13. The data is reproduced at 9, and the output switching SW 11 is switched to the d side. The signal reproduced by the video head 9 is input to the VTR unit 8, the VTR unit 8 enters the reproduction mode (hereinafter, referred to as VV system), and is output from the output terminal 12 via the output switching SW 11.
