PROBLEM TO BE SOLVED: To record even an static image file or the like in addition to a moving image file while maintaining compatibility to a DVD video format, e.g., in application to a digital versatile disk (DVD) regarding an optical disk device, an optical disk recording method, the program of the optical disk recording method, and a recording medium recording the program of the optical disk recording method. SOLUTION: A UDF area, a DVD video area, and an extension file area are set on the information recording surface of an optical disk. An extension file and information necessary for reproducing the extension file are recorded in the extension file area. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To enable a recovery operation when reading of a fixed address for management information recording becomes impossible on a rewritable optical disk. SOLUTION: Padding is executed for each creation of one VTS to secure the recording areas of new TMP - VMGI, the VTSI of a subsequent title, and VTSM VOBS. By recording new TMP - VMGI after the VTS for each creation of one VTS, TMP - BVMI is recorded on a place added to the VTS. Thus, even when the reading of management information becomes impossible because of updating which exceeds media rewriting strength in the TMP - VMGI recording area of the innermost side, the management information is read from TMP - VMGI recorded in the other recording area, and finalization is executed.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk apparatus, a method for recording an optical disk, a program for the method for recording the optical disk, and a recording medium with recorded program for the optical disk recording method for carrying sufficient extendability so as to record even a file for a still picture or the like other than a moving picture. SOLUTION: This invention permits to access individual management information through guide information of an extension file and assigns an identification code CAT ID indicative a type of a corresponding extension file and information CAT INFO TYPE of a recording form for the management information to the guide information of the extension file.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk device (ODD) which can be applied to a digital versatile disk (DVD) device e.g., sufficiently adaptive to various kinds of reproducing devices and records files of still pictures also in addition to moving pictures and to provide a control method for the ODD, a program for the ODD control method, and a recording medium with the program for the ODD control method recorded thereon. SOLUTION: The ODD is applied to an ODD for recording a set of a moving picture file based on a specific format and management information for managing the moving picture file in an optical disk, a set of an extended file other than the moving picture file based on the specific format and extension management information for managing the extended file is recording in the optical disk, and when at least the extended file recorded in the optical disk is a file of a sort different from extended files already recorded in the optical disk, driver software for decoding the extended file is recorded in the optical disk in relation with the extended file.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk recording apparatus capable of recording even a file of a still picture or the like other than a moving picture on an optical disk and attaining free space recording by managing a free space to thereby record information to the free space from which information having been recorded in optional recorded areas is deleted. SOLUTION: The optical disk recording apparatus manages a DVD video file of a DVD-RW medium adopting the ROW (restricted over write) system by using a temporary VMGI (TMP-VMGI), manages an extended file such as a JPEG file other than the DVD video file by a intermediate management information (TMP-EXTI), adds free area management information (TMP-SBM) used for the UDF (universal disk format) or the like to the temporary VMGI (TMP-VMGI) to thereby manage free areas even when extension files such as the DVD video file and the JPEG file are recorded in an intermingled way, allows a user to recognize the free areas by the TMP-SBM information and ensures compatibility with a reproduction exclusive optical disk through finalizing processing.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk device, a recording method of the optical disk, a program for the recording method of the optical disk, and a recording medium with the program for the recording method of the optical disk recorded thereon applicable to a DVD device and capable of recording a file of still pictures or the like in addition to moving pictures. SOLUTION: In this invention, the format of information for use in management to be recorded in a set with a file is switched in accordance with the attribute of the file. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To increase the reliability of TIA(track information) of ITI(insert and track information) of a DV format (format used for a digital video tape recorder). SOLUTION: Three block data reproduced from the TIA area of the ITI sector of a video tape are stored in registers 26, 27 and 28. In a majority decision circuit 29, when no error flags are set up in any of these three registers 26, 27 and 28 and data are coincident with each other for two or more, the coincident data are sent to the register 30 of a next stage.
Abstract:
PROBLEM TO BE SOLVED: To record even the file of a static image or the like in addition to a moving image by effectively using an information recording surface, e.g., in application to a digital versatile disk (DVD) regarding an optical disk, the recording method of an optical disk, the program thereof, and a recording medium for recording the program. SOLUTION: Extension files EF1 and EF2 and extension file information EX are recorded in a group. Thus, the extension file information EX of the other group is indicated by area management information. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To surely play an optical disk and to write once data thereon, for example, when the information recording surface of the optical disk is managed by a management system until finalization regarding an optical disk device, an optical disk recording method, a program for the optical disk recording method, and a recording medium on which the optical disk recording method is recorded. SOLUTION: A management system KA is recorded so as to trace the management system KA from management information TV recorded in a fixed area. When the management system KA become difficult to be reproduced, the management system KA is rerecorded in another area, and the recorded management information TV is correspondingly updated.
