A software-driven method for the initialization of re-writable optical media is provided. Embodiments include a software-driven method for the formatting of re-writable optical media to include defining a file system and writing a UDF reader to the optical media to enable implementation on a plurality of optical media devices in a plurality of operating system environments. The re-writable optical media is initialized using either user data or initialization patterns in a background operation to allow user interaction with the optical media during initialization. Methods are provided for multi-track capabilities of the optical media. Prior to initialization of the entire media space of an optical media, a session can be closed to enable compatibility of a partially initialized media in a ROM device. Further methods are provided to re-open a closed session to complete initialization of the media space.

Method and apparatus for formatting and initialization of re-writable optical media using multiple tracks

A software-driven method for the initialization and defect management of re-writable optical media is provided. Embodiments include a software-driven method for the formatting of re-writable optical media to include defining a file system and writing a UDF reader to the optical media to enable implementation on a plurality of optical media devices in a plurality of operating system environments. The re-writable optical media is initialized using either user data or initialization patterns in a background operation to allow user interaction with the optical media during initialization. Data integrity is managed over the life of the re-writable optical media through use of a write count table with entries corresponding to each packet written to the re-writable optical media and tallied to prompt packet verification upon a pre-determined number of user writes to the packet.
