| 摘要 |
An apparatus and method for defect management of optical disks is disclosed. The apparatus can use existing pre-pit data on the disk to perform defect management, thereby upgrading defect detection efficiency and data access reliability. The apparatus reads the pre-pit data corresponding to a data block from the disk, and performs ECC decoding thereon. Next, the apparatus determines if the pre-pit data is defective according to the decoding result, thereby deciding whether to access the data block subsequently.
