Patent ID: 7392101

Claim:
A multi-track digital recording/reproducing apparatus for recording and reproducing digital audio data by using multiple tracks, comprising: a recording track-setting section that sets each of a plurality of tracks to one of a recording ON state and a recording OFF state in response to operation by user; a mute track-setting section that sets each of a plurality of tracks to one of a mute ON state and a mute OFF state, in response to operation by user, the digital audio data being recorded on the tracks set to the recording ON state while the recorded digital audio data being reproduced from the tracks set to the mute OFF state, wherein each track is settable to the recording ON state and the mute OFF state simultaneously; a reproducible track number-determining section that determines a reproducible number indicating a number of tracks that can be reproduced simultaneously, said reproducible number determined based on the number of tracks set to the recording ON state; and a reproducing track number-limiting section that limits a number of tracks to be set to the mute OFF state based on said number of reproducible tracks, wherein said reproducing track-number limiting section automatically changes at least predetermined one of the tracks from the mute OFF state to the mute ON state when said recording track-setting section increases the number of tracks set to the recording ON state and said reproducible number decreases below the number of tracks set to the mute OFF state, said reproducing track number-limiting section inhibits said mute track-setting section from setting more than said reproducible number of tracks to the mute OFF state.
