A method for recording and reproducing information, including plural channel audio signals on and from a recording medium. A sampling operation at a predetermined sampling frequency is respectively performed against plural channel audio signals, a modulation operation of a predetermined modulation system is performed respectively for each of a plurality of channels of the sampled data, an identification code identifying each channel is added to each of plural channel coded information signals, and subsequently the coded information signals are multiplexed by a time division multiplexing operation and recorded on the recording medium, together with one channel analog audio signal or by themselves. At the time of playback, at least two of the plural channel coded information signals designated by a selection command or at least two of the plural channel coded information signals and the one channel analog audio signal designated by the selection command selectively decoded arbitrarily using the identification code, and a reproduction signal is generated by mixing the two channels of audio signal. With this feature, a single disc can be used for recording a program having multilingual audio signals.
