Abstract:
A disc-shaped recording medium recording apparatus for recording data in a disc-shaped recording medium having a plurality of sectors, said disc-shaped recording medium recording apparatus comprising:a coding means for coding the data into error detection and correction coded data aligned in both row and column directions, and segmenting said error detection and correction coded data into a plurality of segment coded data;means for recording each of said plurality of segment coded data to a sector in a first recording area (ADS) of the disc-shaped recording medium;defective sector discrimination means for determining whether a sector is a defective sector by reproducing said segment coded data recorded in said sector; anddefective sector substitution means, which, in the case where said sector is determined to be a defective sector, skips only the defective sector and records said segment coded data in and after the defective sector in the following sectors by successively slipping one by one sector,wherein in the case where there remain no sufficient sectors in the first recording area (ADS) as a result of the sector slipping substitution, the data for the defective sector is shifted to be recorded to a second recording area (ASS).
