A disc recording apparatus (A) for writing data onto a sector providing a recording area (B2) on a magneto-optical disc (B) performs a retry upon failure in the writing until a predetermined number of retries is reached, treats the sector as a defective sector upon failure in the last retry of the predetermined number of retries, and writes the data onto another sector. During a physical formatting, A CPU (11) records in medium management information (B1) on the recording disc (B) a retry count as retry count information for each of recovered sectors recovered from the failure through success in the writing of data during the retry. When actual data is written onto the physically formatted magneto-optical disc (B), and upon detection of a defective sector failed in the writing of the actual data, the CPU (11) selects a replacement sector for the defective sector. The replacement sector has a retry count stored as the retry count information smaller than that of the defective sector.
