摘要： 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.

摘要： The present invention aims to, when recording pulse information are transmitted to a laser driver lying over a pickup through an optical disk, reduce the number of transmission paths or lines from a conventional transmission method and avoid degradation of recording performance due to transmission path characteristics upon fastening of a recording speed thereby to provide stable recording performance at high-speed recording. The invention of the present application reduces the number of transmission signals by encoding multi-level laser pulse information transmitted by the laser driver. Further, gray codes are used for encoding to reduce constraints of skew between bits. Furthermore, encoding is executed using each state transition and the state transitions are switched according to each recording mark and space, thereby reducing the occurrence of a short pulse on each transmission path. In addition, the presence or absence of the encoding is switched to enable signal transmission, thereby making it possible to make compatible adaptation to complex laser pulse information and adaptation to high-speed recording.

摘要： When, in the course of recording data to a disk for each basic recording unit, the recording is stopped in the middle of a basic recording unit, data of the basic recording unit of the recording that was stopped remain held in memory. When recording resumes, the recording operation is restarted sequentially from the remaining data held in memory from the position at which recording was stopped. When the remaining data cannot be recorded, dummy data are recorded instead and playback is performed, skipping the dummy data section.

摘要： An apparatus for recording and reproducing digitally compressed data in the form of divided data in and from a recording medium. A data processing circuit adds reference time information indicating an output reference time during a reproducing process to each of the divided data in the digitally compressed data. A recording circuit records the divided data with the added reference time information in the recording medium. A reproducing circuit reproduces the divided data with the added reference time information from the recording medium. A rearranging circuit rearranges and outputs the reproduced divided data on a time axis according to the reproduced reference time information such that a time interval between adjacent divided data as outputted from the rearranging circuit is equal to a time interval between respective output reference times of the adjacent divided data.
