    摘要： The present invention provides a method or an apparatus for recording data additionally by acquiring replacement data easily even when the latest disc management information cannot be read out of the disc. When updating TDMS (Temporary Disc Management Structure), an update reason of a corresponding TDMS and a TDDS (Temporary Disc Definition Structure) start address in a previously recorded TDMS are recorded in disc management information as additional information. If the latest TDMS cannot be read out of the disc but the additional information can be read out, the additional information are referred to determine the latest LRA for use in additional data recording on the disc.

    摘要： A recording method and a recording apparatus capable of optimally arranging data on a write-once type optical disc. In a write-once type optical disc recording method with respect to a disc having a read-in, a user area, and a read-out by employing defect management information, the user area is divided into 3, or more pieces of R-zones; at least 2 recordable R-zones having recordable areas are present. When an unrecordable R-zone having no recordable area is present on the read-in side rather than two, or more pieces of the R-zones among the R-zones having the recordable areas, a linear replacement destination of a logical overwriting is determined to such an R-zone other than an R-zone having a recordable area, which is located adjacent to the unrecordable R-zone.

    摘要： A digital data recording/reproducing method includes the steps of: interleaving data on a PI code for each PI code of a 208-row ECC block; and converting a short burst error into random errors by dispersing errors on the PI codes. Moreover, the digital data recording/reproducing method increases correction capability against several bytes to several tens bytes of errors generated at random without changing burst error correction length by performing this processing for respective PI codes by using interleave rules that are different as much as possible from one another.

    摘要： A recordable optical disc includes a user area and a management information area. User data is recorded in a physical block used as a single unit, and the space bit map is recorded in the management information area. Integrity verification processing is performed for each of recording status information so as to verify the integrity of the recording status information indicating a recording status of the physical block and the recording status of the physical block on the recordable optical disc. The necessity of the integrity verification processing is determined by reading out the status information indicating the necessity of the integrity verification processing. When the integrity verification processing is determined to be necessary, the integrity verification processing is carried out for unverified recording status information of the recording status information of the space bit map.
