ABSTRACT:
A first reproduction circuit reproduces a digital stereo audio signal from a signal which is read by means of a pickup from a disc loaded at a playback position, and a second reproduction circuit reproduces an analog audio signal from the signal read by the pickup. When the disc loaded at the playback position is identified as being a Laser vision Disc with Digital sound (LDD) disc, the stereo audio signal outputted from the first reproduction circuit is mixed with the analog audio signal outputted from the second reproduction circuit, such that a vocal portion of a reproduction can be reproduced together with an accompaniment portion of the reproduction, in a stereo mode.
