    摘要： A recording method of the present invention includes the steps of: receiving a write instruction which specifies at least a logical sector in which data is to be written; determining whether the logical sector specified by the write instruction corresponds to a recorded physical sector or an unrecorded physical sector (S1111); when it is determined that the logical sector specified by the write instruction corresponds to an unrecorded physical sector, writing the data into the unrecorded physical sector (S1112); and when it is determined that the logical sector specified by the write instruction corresponds to a recorded physical sector, writing the data into an unrecorded physical sector other than the recorded physical sector (S1113), generating a remapping table including remapping information which remaps an original address of the recorded physical sector to a remapping address of the selected physical sector, and writing the remapping table on the write-once disc (S1114).

    摘要： A file system is enabled to use a Metadata Partition instead of VAT for write-once discs, and is provided by a pseudo-overwrite method with a plurality of tracks especially for metadata and file data. On applying this invention to a drive apparatus that supports pseudo-overwrite media, the file system distinguishes data to overwrite from data to append (S1701). When the data is newly written to a logical sector, the drive apparatus writes the data to a physical sector to which the logical sector corresponds (S1703). When the data being overwritten is data stored in the logical sector, the data is written to the other unrecorded physical sector in the volume space (S1704), and remapping information is written (S1705). The remapping information specifies the original address of the physical sector, and the remapping address of the physical sector in which the data is written.

    摘要： An apparatus and method of addressing data losses when power to a digital recorder is unexpectedly interrupted during recording, and the file management information needed to play back digital content is not completely written to a disc. The recovery process for correcting inconsistencies between the AV data and management information left on the disc is time-consuming. By recording the recovery data used for the data recovery process when power is turned on again, the management information can be recompiled based on the recovery data. Thus, inconsistencies between the AV data and management information can be corrected. Additionally, AV data and recovery data in this case can be written alternately to contiguous areas on disc.
