ABSTRACT:
An optical storage update module extends the life of re-writable optical medium, such as DVD+RW optical storage disks, by identifying data units having and lacking updates for information writes to commonly used portions of the optical medium and then writing the information by writing data units having updates and restricting the writing of at least some of the data units lacking updates. For instance, a stored file system structure of an optical medium, such as a UDF random writable file system, is read from the optical medium and compared with an updated file system structure to identify and write to the optical medium substantially only those data units changed by the updated file system structure. In one embodiment, file structure updates are written to the optical storage medium with Read Modify Write operations.
