Abstract: If a recording error has occurred during RAW, then subsequent recording reproducing processing is omitted in a predetermined range, and all blocks omitted in the processing are handled as defective blocks, DFL-registered, and recorded in a replacement area. As a result, it becomes possible to hold down the number of times of recording processing accompanied by seek processing in the RAW processing, and transfer rate lowering can be solved.

Abstract: Disclosed is a method for managing a defect of an optical disc. In the method, when a host requests data of an optical disc inserted into an optical disc drive (ODD) included in a device to be integrated with a solid state drive (SSD), an address of the requested data is compared with contents contained in defect management information managed within the SSD, and the requested data is read from the optical disc or from the defect management information according to a result of the comparing. The defect management information may include optical disc identification information, address information, defect type information and data of a corresponding address. When the optical disc is inserted into the ODD, defect management information regarding the optical disc may be generated and stored in the SSD. Accordingly, Read Delay or Read Fail, resulting from a defect of the optical disc, can be obviated.
