Filed:

Nov 23, 1999

Appl. No.:

09/447964

Inventors:

Michael Scott McMurdie - Pleasanton CA
Kenneth R. James - Sunnyvale CA

Assignee:

Roxio, Inc. - Milpitas CA

International Classification:

G06F 1328

US Classification:

711112, 710 52, 710 57

Abstract:

A method for handling buffer under-runs during the recording of files to an optical disc is provided. The method includes reserving a track for recording a file system associated with recording of one or more files on the optical disc. Then, the method moves to record the one or more files onto the optical disc in a track that logically follows the reserved track. In case of a buffer under-run, the method proceeds to close a current track and begin a following track after a gap, thus inserting a gap for each buffer under-run. Path tables and directory descriptors of the file system are then written after recording the one or more files. A volume descriptor sequence of the file system is recorded in the reserved track at a time after recording the path tables and the directory descriptor. The file system can also be as defined in the Joliet standard and the UDF standards.

Roxio, Inc. - Santa Clara CA

International Classification:

G11B 700

US Classification:

369 5311, 369 4728, 369 4736

Abstract:

Methods for maximizing recording efficiency when recording data from a source to an optical media are provided. In one example, a method includes identifying a list of files to be recorded, and then generating a plurality of recording orders for the list of files. A plurality of writing speeds supported by a target optical media recording device are determined, and then each of the plurality of recording orders for the list of files at each of the plurality of writing speeds are evaluated to determine the amount of system cache required and the projected recording time for recording the data. The method selects a single recording order and a single writing speed that minimizes system cache utilization and minimizes actual recording time to record the data from the source to the optical media.

Assignee:

Sonic Solutions - Santa Clara CA

International Classification:

G06F 17/30

US Classification:

707205, 707101

Abstract:

Methods and media for pre-mastering in preparation for recording data files to optical media are provided. In one example, a method for pre-mastering includes receiving a selection of data files to be recorded to an optical media and generating a database in which to list the selection. The database is populated with the selection of data files which are identified by file node and listed in alphabetical order by directory. The method provides for accessing a file in the database, verifying a source location of the accessed file, verifying an integrity of the accessed file, and determining a destination location for the accessed file. The determining of the destination location includes determining a logical block to which at least a portion of the accessed file is to be recorded on the optical media.

International Classification:

G06F 7/00

US Classification:

707102000

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.
