More Information
Summary:A storage file system is provided for data stored on a storage medium, and particularly for storage of data on optical disc storage medium. Each successive or alternate file of data included in the storage medium is represented by a respective allocation extent list with each allocation extent identifying locations of data segments for each file. Data in some data segments or portions of data segments may be shared by two or more files with each file having a respective allocation extent list entry referencing that segment and each such allocation extent maintaining byte-accurate pointers to the start and end of the data relevant to each file within the data segment. An allocation space table containing respective entries for each reference to a data segment or portion of a data segment, and optionally a free-space table identifying those data segments or portions of data segments available for rewriting, may be provided to allow for rapid reclamation of free within the storage medium.
