ABSTRACT:
Methods, software, apparatus, and systems for reading a recordable optical disc. The method generally comprises the steps of (a) determining whether a lead-in area on the disc contains valid lead-in data and, when the lead-in area does not contain valid lead-in data, and (b) searching an area on the disc (e.g., searching for directory data, such as RSAT or VAT data). The present invention advantageously allows a disc playback device (e.g., a DVD player) to locate disc type information even on discs that are unfinalized (e.g., where no lead-in data has been recorded in the lead-in area of the disc).
