Optical disk device method for detecting and replacing a defective sector within a block containing recording data and error correction data on an optical disk |
摘要 |
An apparatus and method for detecting and replacing a defective sector on an optical disk. Recording data and error correction data are recorded on an optical disk at a manufacturing time or an initial time. The recorded data and the error correction data are reproduced in units of one sector. A defective sector is determined when address data in an address field cannot be reproduced or when a number of errors in at least one sector exceeds a specified value. Address data of the defective sector is recorded in a defect list on the optical disk. Recording data and error correction data are successively recorded on the optical disk in a plurality of successive block areas. Defective sectors are skipped and recording data and error correction data are recorded in a unit of one block beginning in a next sector area. When a defective sector is detected after recording the recording data and the error correction data at a time other that the initial time or the manufacturing time, the recording data and the error correction data are recorded in a block area being different than a block area containing the defective sector.
