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.
