The No. 1 data stored in the second voice storage means 17 is read and input to the voice demodulation means 20 through the b contact of the data read switching means 19. The voice demodulation means 20 demodulates the 1st data and outputs the 1st voice signal from the voice output terminal 21 (step 57). When the reading of the No. 1 data is completed, the process shifts to No. 2. However, since the No. 1 and No. 2 and subsequent audio data are the same, the No. 1 data is repeatedly read and the No. 1 audio signal is output (step 58). When the reading of the last number is completed, the control means 23 switches the data read switching means 19 to the c contact. Third voice storage means 1
The subsequent performance data stored in No. 8 is read and input to the voice demodulation unit 20 through the c contact of the data read switching unit 19. The audio demodulation means 20 demodulates the subsequent performance data and outputs the subsequent performance audio signal from the audio output terminal 21 (step 59).

In this way, the voice signal is output and the image signal with lyrics is output to reproduce the karaoke.

When the disc is exchanged, even if the karaoke disc is used without exchanging the disc, the image data is recorded, so that the same effect can be obtained by reproducing the image data area 6.

[0023]

As described above, according to the present invention, since the audio data is divided and recorded on the disc into the three parts of the prelude, the No. 1 and the afterplay, the No. 1 audio data can be repeatedly used. There is no need to record voice data after the turn. That is, it is possible to record a larger number of songs on one disc than in the conventional case, and it is possible to reduce the number of karaoke album discs.

When the audio data for one song recorded on the disc is read into the audio storage means, it can be read in a short time.

Further, since the total storage capacity of the audio storage means can be reduced by the audio data of the second and subsequent audio data, the cost of the karaoke reproducing apparatus can be reduced.

When playing only No. 1 or No. 2 in karaoke and ending, it is possible to easily perform with prelude and postlude, and it is possible to realize a very effective and various usage.

Since the disc can be exchanged before the image is reproduced, the karaoke of the same song can be played with the image having different contents. This is a karaoke playback device that can use the image of a laser disk that has been used in the past as a background for karaoke, and can effectively utilize conventional image software assets.
