ABSTRACT:
A recording/playback apparatus for a DVD on which a VOB and a management file of the VOB are recorded. When detecting a failure in the management file, the recording/playback apparatus changes the state of the DVD to: (a) a first state in which reading/writing of the DVD is available; (b) a second state in which reading/writing of the DVD is available but the VOB cannot be played back; or (c) a read only state, in accordance with the detected failure. When the state of the DVD changes to the second state, the recording/playback apparatus writes a new VOB onto the DVD. When the state of the DVD changes to the read only state, the recording/playback apparatus plays back the VOB recorded on the DVD.
