Abstract: Additional recording is performed on a recording medium without using a VAT technique. An area including the 256th logical sector is reserved at disc initialization time, and additional recording is performed from this reserved area and after. Additional recording is performed by writing packets from a logical sector immediately after a recorded area (including the reserved area), and AVDP is recorded into two places having the last logical sector number N of a packet structure and a logical sector number less than 256 sectors from N, and thus additional recording in compliance with the UDF is possible after that. At the time of finalization, AVDP is recorded in the 256th logical sector, a surplus area in the reserved area is subjected to padding to ensure wide compatibility with playback-only apparatuses.

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.
