Abstract
In playing back data in an optical disk device, to perform high-speed data playback with a low number of playback retries even if an error occur when data is being read. In reading data composed of ECC blocks, if a data error occurs during a read operation, the data from sectors for which PI error correction can be performed is left alone. Playback retries using different playback conditions are performed just on the sectors for which PI error correction can be performed. Thus, the playback retry count can be reduced.
