Multi-session optical media

Abstract

A multi-session optical media has data recorded thereon. The multi-session optical media is recorded in compliance with UDF 1.02, and the data in each session of the multi-session optical media is accessible by a UDF 1.02 compliant optical media device. A partition space of a subsequent session to a first session of the multi-session optical media is defined to begin at a sector at which the start of a first partition is defined in the first session on the multi-session optical media.

1 . A multi-session optical media having data recorded thereon, the multi-session optical media being recorded in compliance with UDF 1.02 and the data in each session of the multi-session optical media accessible by a UDF 1.02 compliant optical media device, 
 wherein a partition space of a subsequent session to a first session of the multi-session optical media is defined to begin at a sector at which the start of a first partition is defined in the first session on the multi-session optical media.    
   
   
       2 . The multi-session optical media of  claim 1 , wherein a partition space of any session recorded after the first session on the multi-session optical media is defined in reference to an address of a first sector of the first partition space in the first session on the multi-session optical media.  
   
   
       3 . The multi-session optical media of  claim 1 , wherein file system structures to define the partition space of the subsequent session are written to describe data written to the subsequent session and the file system structures are written to define the partition space of the subsequent session to describe data written to a previous session on the received optical media.  
   
   
       4 . The multi-session optical media of  claim 3 , wherein the file system structures include file identifiers and file entries.  
   
   
       5 . The multi-session optical media of  claim 3 , wherein the subsequent session includes the partition space and a volume space.  
   
   
       6 . The multi-session optical media of  claim 3 , wherein user data written to the subsequent session is referenced to the sector at which the start of the first partition is defined in the first session.  
   
   
       7 . The multi-session optical media of  claim 1 , wherein the multi-session optical media is a DVD.  
   
   
       8 . A multi-session optical media having data recorded thereon, wherein a partition space of any session recorded after a first session on the multi-session optical media is defined in reference to an address of a first sector of a first partition space in the first session on the multi-session optical media.  
   
   
       9 . The multi-session optical media of  claim 8 , wherein the multi-session optical media is recorded in compliance with UDF 1.02.  
   
   
       10 . The multi-session optical media of  claim 9 , wherein the data in each session of the multi-session optical media is accessible by a UDF 1.02 compliant optical media device.  
   
   
       11 . The multi-session optical media of  claim 9 , wherein a partition space of a next session after the first session of the multi-session optical media is defined to begin at a sector at which the start of a first partition is defined in the first session on the multi-session optical media.  
   
   
       12 . The multi-session optical media of  claim 9 , wherein file system structures to define the partition space of a subsequent session are written to describe data written to the subsequent session and the file system structures are written to define the partition space of the subsequent session to describe data written to a previous session on the received optical media.  
   
   
       13 . The multi-session optical media of  claim 12 , wherein the file system structures include file identifiers and file entries.  
   
   
       14 . The multi-session optical media of  claim 12 , wherein the subsequent session includes the partition space and a volume space.  
   
   
       15 . The multi-session optical media of  claim 12 , wherein user data written to the subsequent session is referenced to the sector at which the start of the first partition is defined in the first session.  
   
   
       16 . The multi-session optical media of  claim 12 , wherein the multi-session optical media is a DVD.
