    摘要： To enable a physically rewritable disc to be appropriately used as a write-once type.When the rewritable disc is used in rewritable application, the position where writing of a predetermined data unit (for example, an ECC block) in data is started is set to a first position with respect to a reference position to record or play back the data. In contrast, when the rewritable disc is used in write-once application, the position where writing of the predetermined data unit in the data is started is set to a second position different from first position to record or play back the data. The position where writing of the data is started in the rewritable application is shifted from the position where writing of the data is started in the write-once application to disable rewriting of the data recorded on a rewritable recording medium when the rewritable recording medium for the write-once application is loaded in a recording-playback apparatus that does not assume the use of the rewritable recording medium in the write-once application.

    摘要： To realize a disk drive device capable of setting optimum recording power by obtaining amplitude information of a reproduced signal even when low recording power is used. A disk drive device for recording and reproducing data on/from an optical disk is provided with: a Viterbi decoding means for performing Viterbi decoding on a reproduced signal reproduced from an optical disk to decode data and creating status data representing a status transition in the Viterbi decoding; and a quality index creation means for calculating a differential value between an amplitude reference value corresponding to the status transition recognized from the status data and a reproduced signal value created by digitizing the reproduced signal and creating a quality index value representing quality of the reproduced signal based on the differential value. The quality index creation means obtains a quality index value with the amplitude reference value fixed to a prescribed value, to create an amplitude evaluation value representing the amplitude of the reproduced signal.

    摘要： A recording medium comprising a data-recording surface is formed of plural tracks, with a respective track having a data section in which units of data are to be recorded. Only one header section is provided before the data section, the header section serving as a reference position for dividing said track into sectors. The header section is defined by prepits formed in the data-recording surface. As a result, data is recorded in the header section at such a high density that the header data is reproduced with super resolution.
