ABSTRACT:
A data storage medium, and an apparatus and method for formatting the same. The medium is preferably characterized as a hybrid or recordable optical disc, and includes a pre-recorded storage area and a recordable storage area. The pre-recorded storage area stores file system data which identifies at least one file to be stored to the recordable storage area during a subsequent recording session, with the file system data having been stored to the pre-recorded storage area during a previous recording session. The file system data further preferably identifies at least one file stored to the pre-recorded storage area during the previous recording session. The pre-recorded and subsequently stored files are preferably disposed within the same logical track on the medium. The pre-recorded file system data includes entries for the subsequently added file(s), and eliminates the need for multiple copies of the file system on the medium.
