Abstract:
A method accesses and updates information from a library of optical discs and includes a step of cataloging optical discs. The cataloging step includes the generation of a unique value for each of the cataloged discs. The unique value is produced by iteratively reading data from each disc and iteratively combining the data. The cataloging step includes the generation of catalog data streams. The catalog data streams include fixed length data representing file and directory attributes and variable length data representing file names and directory names. The method includes the further step of producing limited depth catalogs representing file and directory information on the optical discs. The limited depth catalogs have a fixed number of subdirectory levels and file types. The fixed number is selected by a user, and the file types are selected by a user.
