INFORMATION RECORDING MEDIUM, APPARATUS AND METHOD FOR PERFORMING AFTER-RECORDING ON A RECORDING MEDIUM

摘要

A recording medium comprises an audio stream capable of being replaced with an after-recorded audio stream and audio attribute information (e.g., bit rate information indicative of a bit rate of the audio stream). In the recording medium, a plurality of audio streams may be stored. At least one of the audio streams may be the audio stream capable of being replaced with an after-recorded audio stream. The audio stream capable of being replaced with an after-recorded audio stream may be an audio stream which is provided for an audio stream carrying original audio data and having the same audio attribute as the audio stream carrying original audio data. A recorder includes a checking mechanism for checking in-advance the possibility of after-recording operation of the recorder of the audio stream to be after-recorded with reference to the bit rate information of the audio attribute information.
