Abstract
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.
