Claim 1
Independent Claim
212 words
A recording and/or reproducing method for effecting one of (i) recording an audio signal on a recording medium by causing the audio signal to correspond to a video signal, (ii) recording an audio signal on a recording medium by causing the audio signal not to correspond to a video signal and (iii) reproducing at least one of an audio signal and a video signal recorded on a recording medium, said method comprising the steps of: indicating one of (i) recording of the audio signal on the recording medium by causing the audio signal to correspond to the video signal and (ii) recording of the audio signal on the recording medium by causing the audio signal not to correspond to the video signal; recording first data indicating that the video signal corresponding to the audio signal exists on the recording medium together with the audio signal, when said indicating step indicates that the audio signal is recorded on the recording medium corresponding to the video signal; and recording second data indicating that the video signal corresponding to the audio signal does not exist on the recording medium together with the audio signal, when said indicating step indicates that the audio signal is recorded on the recording medium not corresponding to the video signal.
Claim 2
Dependent Claim
212 words
A recording and/or reproducing method for effecting one of (i) recording an audio signal on a recording medium by causing the audio signal to correspond to a video signal, (ii) recording an audio signal on a recording medium by causing the audio signal not to correspond to a video signal and (iii) reproducing at least one of an audio signal and a video signal recorded on a recording medium, said method comprising the steps of: indicating one of (i) recording of the audio signal on the recording medium by causing the audio signal to correspond to the video signal and (ii) recording of the audio signal on the recording medium by causing the audio signal not to correspond to the video signal; recording first data indicating that the video signal corresponding to the audio signal exists on the recording medium together with the audio signal, when said indicating step indicates that the audio signal is recorded on the recording medium corresponding to the video signal; and recording second data indicating that the video signal corresponding to the audio signal does not exist on the recording medium together with the audio signal, when said indicating step indicates that the audio signal is recorded on the recording medium not corresponding to the video signal.
