Info

If the last session on a CD does not contain a valid UDF file system, the disc is not a UDF disc. Only the UDF structures in the last session, and any UDF structures and data referenced through them, are valid. The UDF session may contain pointers to data or metadata in other sessions, pointers to data or metadata only within the UDF session, or a combination of both. Some examples of UDF Bridge discs are shown below. Access to LSN=16+x Multisession UDF disc Access to LSN=256 16 sectors 256 sectors LSN=0 First Session N - 256 16 sectors 256 sectors LSN=S 1 st Recorded Track in the last session : Volume recognition area : Anchor point CD enhanced disc 1 st session 2 nd session UDF Session Playable by conventional CD-Player Used by UDF UDF 2.00 April 3, 1998 119
