Abstract: A data recording structure supporting an AVCHD format is provided. The data recording structure allows a playing process, an editing process and a write-once recording process to be quickly performed. When data recording is performed in a data recording format having a layered management structure such as an AVCHD format, identification information is stored in an index file containing index information for record data. The identification information is needed to perform one of the playing process on the record data, the editing process on the record data and the write-once recording process on data. This arrangement eliminates the need for reading a variety of files and retrieving information when one of the record data playing process, the record data editing process and the write-once recording process is performed. Each process is thus quickly performed.

Abstract: A stream on a recording medium is divided into parts, and is subjected to rearrangement editing while the compatibility with a playback-only device is maintained. By adopting a division processing procedure of a play item, rearrangement processing of a stream for each chapter is achieved. In a product specification, a plurality of real play lists are put together into a series of chapter groups to be presented to the user, and thus there are cases where rearrangement of chapters are closed in the same play list, and cases where the rearrangement extends over a plurality of play lists. Moreover, rearrangement editing, which moves a chapter between real play lists, between virtual play lists, and further from a real play list to a virtual play list, is performed.

Abstract: Before each content file is recorded first to a recording medium, a flag indicating a recording state of a content file is generated corresponding to a physical area where an index file can be continuously recorded. An index file is generated which associates attribute information with the generated flag added thereto with real data of each content file, and the generated index file is recorded to the recording medium. Since fragmentation of the physical area where the index file is recorded is restrained to a minimum level, a high-speed reading operation is realized.

Abstract: In order to form a thin film having a high aspect ratio, a space between a target within a vacuum chamber and a substrate table is enclosed by an anode electrode and earth electrodes. The anode electrode is positioned on the side of the target, and a positive voltage is applied. The earth electrodes are positioned on the side of the substrate table and are connected to earth potential. A trajectory of sputtering particles curved in the direction of flying off by the anode electrode is corrected and is made incident in a perpendicular manner to a surface of the substrate on the substrate table. The amount of sputtering particles incident to the surface of the substrate can therefore be increased and made perpendicularly incident; and a thin film of a high aspect ratio can be formed.
