Information recording medium, information recording/playback method, and information recording/playback apparatus

摘要

There is provided a system configured to prevent recording contents of various broadcasting schemes from being recorded together on a single recording medium while supporting various broadcasting schemes. An optical disc used here can record a digital stream complying with a predetermined digital broadcasting scheme and including specific information APP_NAME corresponding to a broadcasting scheme to be recorded. The broadcasting scheme to be recorded is checked (ST1116). If another digital stream has already been recorded on the optical disc, its broadcasting scheme is detected from APP_NAME, and is compared with that of the stream to be recorded. If these broadcasting schemes are different (NO in step ST1120), recording is aborted (ST1124).
