Abstract: Methods and media for efficiently processing data to be recorded to optical media are provided. In one example, a method for processing data to be recorded to optical media is disclosed. The method includes receiving a request to record data to optical media, and mapping a source path for the data if the file path has not been previously mapped or associating the data to be written with a source path, which has been previously mapped, wherein the source path includes a complete path from a root directory to a file location of the data. The method further includes saving the source path for the data to a file system database for efficiently processing data selected to be recorded to the optical media, and retrieving the source path from the file system database in a single step without successive tracing to the root directory to record the data to optical media.

Abstract: Methods and media for pre-mastering in preparation for efficient recording data files to optical media are provided. In one example, a method for recording data files to optical media is provided. The method includes receiving a request to write a selection of data files to an optical media. The method also includes generating a file node for each file in the selection of data files, wherein the file node is used to retrieve the each file in a single step from root to file avoiding tracing the each file back through any intermediate sub-directories. The method further includes constructing a database for the selection of data files, the database being configured to list each file in the selection of data files to be written to the optical media, and writing the selection of data files listed in the database to the optical media.

Abstract: A multi-session optical media has data recorded thereon. The multi-session optical media is recorded in compliance with UDF 1.02, and the data in each session of the multi-session optical media is accessible by a UDF 1.02 compliant optical media device. A partition space of a subsequent session to a first session of the multi-session optical media is defined to begin at a sector at which the start of a first partition is defined in the first session on the multi-session optical media.

Abstract: A method for recording data to optical media is provided. A selection of files to record from a source to a destination optical media is received, and an enumeration of the data files to record to the destination optical media is generated. The enumeration of data files includes the determining of whether any source file is in the enumeration of data files to record to the destination optical media more than one time. A destination file path node is mapped for each data file to be recorded to the destination optical media, and the selection of data files is recorded to the destination optical media. The recording includes only one occurrence of any source file in the enumeration of data files to record to the destination optical media.
