Abstract
A software driven method for recording multiple sessions on a rewritable DVD is provided. Examples include a software-driven method for appending data to rewritable DVD disc. A rewritable DVD disc for recording, wherein the rewritable DVD disc contains previously written data is received for appending data. A request to append new data to the rewritable DVD disc is received. A file system for the previously written data is located and includes a pointer to the start of the file system. The file system for the previously written data is then read. The file system is modified to continue pointing to files associated with the previously written data and to generate pointers to files of the new data. An updated file system and the new data to the rewritable DVD disc are logically written after the previously written data. The pointer of the file system is then modified to refer to the updated file system.
