Patent ID: RE38706

Claim:
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; and defective sector discrimination means for determining whether a sector is a defective sector by reproducing said segment coded data recorded in said sector, such that a defective sector is detected by decoding only the error detection and correction coded data within said the segment coded data recorded in said sector; and defective 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.
