PROBLEM TO BE SOLVED: To prevent the mixing of noise into the output voice at the time of reproducing an audio CD. SOLUTION: This disk reproducing device is furnished with an MPEG recorder 50 by which a digital signal of a CD drive 20 at the time of reproducing a video CD is separated to a digital video signal and a digital audio signal, after that, these signals are respectively decoded, and also an audio D/A converter 71 is provided at the post stage side of the MPEG recorder 50 for converting the digital audio signal to the analog signal and outputting it. In this case, a switch IC 80 is arranged at the front stage side of the MPEG audio recorder, and since the arrangement is made so that an output of the switch IC 80 at the time of reproducing the video CD is changed over to the MPEG decoder 50 by a system controller 30 and an output of the switch IC 80 at the time of reproducing the audio CD is changed over to the audio D/A converter 71, the clock timing does not lose at the time of reproducing the audio CD, then the noise is reduced. |
