摘要： A magneto-optical disc device (1) writes data, for each sector, onto a magneto-optical disc (2) using an optical head portion (21) which outputs light onto the magneto-optical disc, at which time the data on the magneto-optical disc (2) is erased and after data is erased, data is written onto the magneto-optical disc (2), and the original data is then verified against the written data for each sector. When verifying the original data against the written data, if a verification error is detected for a sector, position information for the sector on the magneto-optical disc (2) in which a verification error is detected is stored in memory (16). Data verification is continued even when a verification error is detected, and at the end of data verification, data verification is again performed for sectors in which verification errors are detected, based on the position information for sectors stored in memory (16).
