OPTICAL DISC DEVICE, OPTICAL DISC RECORDING METHOD, AND REPRODUCTION METHOD |
摘要 |
Even when recording data which is continuously inputted at a high speed, it is possible to correct a recording error and reproduce preferable AV data without a noise upon reproduction. A recording error detection circuit (14) detects an error generation upon recording according to the fluctuation of amplitude of a tracking error signal or a focus error signal. A recording signal processing circuit (6) again records (performs skip recording) the same data in a region adjacent to a region where a recording error has occurred. When performing the skip recording, address information contained in the recording data is rewritten into address information on a new recording region. Moreover, an identifier (skip mark) indicating that a recording error has occurred is added to the pattern of the link region of the recording data. |
