ABSTRACT:
A software driven method for appending data to a rewritable optical disc is provided. The method includes detecting a rewritable optical disc, and the rewritable optical disc contains a first written session with a file system and an associated volume descriptor. The method then detects a request to write a new session to the rewritable optical disc. Now, it is determined that the new session is to be written past a boundary limit, e.g., such as an OS boundary. A new file system for the new session is then generated, where the new file system having an updated volume descriptor. Data for the new session is written and the volume descriptor of the first written session is replaced with the updated volume descriptor.
