Abstract: This invention is a recording medium recording method for an optical disc or the like. Every time one VTS is prepared, padding processing is executed to secure a recording area for new TMP_VMGI following that VTS and for VTSI and VTSM VOBS of the subsequent title. As, every time one VTS is prepared, new TMP_VMGI following that VTS is recorded, TMP_VMGI is recorded at the position that is added to the number of VTSs. Therefore, even when the management information becomes unreadable because of update exceeding the rewriting durability of the medium with respect to the recording area of TMP_VMGI on the innermost side, the management information can be read from TMP_VMGI recorded in the other recording areas and the finalizing processing can be executed.

Abstract: In a ROW-based DVD-RW, a DVD video file is managed according to provisional VMGI (TMP_VMGI) and an extension file other than the DVD video file, such as a JPEG file or the like is managed according to intermediate management information (TMP_EXTI), and temporary space bitmap (TMP_SBM) used in UDF and the like is added to provisional VMGI (TMP_VMGI to record a combination of the DVD video file and extension file such as JPEG file and manage the temporary space. Thereby, the temporary space can be known from TMP_SBM, and even when the extension file has been deleted, the DVD-RW is made interchangeable with a read-only optical disk through finalization. Thus, the present invention allows to record a file of still pictures other than moving pictures and also pad information in a temporary space resulted from deletion of any recorded area.

Abstract: The present invention relates to a recording apparatus for improving operability of a DVD camcorder that performs recording in a video format. When an instruction for starting recording is given at a time T11 and then an instruction for stopping the recording is given at a time T12, a DVD camcorder is brought into a pause state at the time T12. An address and the like of an optical disk at that time are stored in a recording RAM. When an instruction for resuming recording is given at a time T13, the address stored in the recording RAM is read, and rerecording is started at a position on the optical disk which position corresponds to the address. The present invention is applicable to DVD camcorders.

Abstract: A recording apparatus for improving operability of a DVD camcorder, or the like, that performs recording in a video format. When an instruction for starting recording is given at a first time and then an instruction for stopping the recording is given at a second time, a DVD camcorder is brought into a pause state at the second time. An address and the like of an optical disk at that time are stored in a recording RAM. When an instruction for resuming recording is given at a third time, the address stored in the recording RAM is read, and rerecording is started at a position on the optical disk which position corresponds to the stored address.

Abstract: The present invention provides an optical disk drive, optical disk recording method, optical disk recording program and a recording medium having the optical disk recording method recorded therein, applicable to a DVD drive, for example, to permit recording of also a file of still pictures other than moving pictures with a sufficient extension of the recording ability of the optical disk. To this end, individual management information can be accessed via guide information for an extended file in consideration and an identification code CAT ID indicative of the type of the extended file and recording format CAT INFO TYPE of the management information are allocated to the extension-file guide information.

Abstract: The present invention provides an optical disk drive, optical disk recording method, optical disk recording program and a recording medium having the optical disk recording method recorded therein, applicable to a DVD drive, for example, to permit recording of also a file of still pictures other than moving pictures, thereby enabling more effective use of the information recording area of the optical disk and more quick search for desired data. To this end, the address of management information (DK) is identified with reference to a management table (TV) recorded in a fixed area on the optical disk, and a recording format is selected for the management information (DK) to be recorded in combination with an extension file (EF).

Abstract: A recording apparatus and a recording method that can record both moving picture data and still picture data in a form reproducible by various reproducing apparatus. The moving picture data is compressed by an MPEG system by an MPEG encoder (2), formed into data for recording corresponding to a predetermined recording format by a format forming unit (3), and then recorded on a DVD (100). The still picture data is compressed by a JPEG system by a JPEG encoder (6), and recorded on the DVD (100) separately from the moving picture data. In predetermined timing, the still picture data compressed by the JPEG system and recorded on the DVD (100) is read, the still picture data is converted into I-pictures of the MPEG system by a format converting unit (7), and then the I-pictures of the MPEG system are recorded onto the DVD (100) in the predetermined format via the format forming unit (3).
