Recordable optical disk, optical disk recording device, an optical disk reproduction apparatus, and method for recording data to recordable optical disc

摘要

DVD-R recorder according to the present invention demodulates recording speed information (d15) from (30) DVD-R that records the history of the recording power condition recording velocity information, and write strategy. Match when setting recording speed information (d15) demodulation recording speed information with the (d17), I demodulate and (d10) recording power conditions (d6) recording strategy corresponding to (d15) the demodulated recording speed information. Recording pulse decision unit (9) is converted into (d9) recording pulse recording strategy in accordance with (d6) Record pattern (d8). Recording power determining unit (12) to run the OPC based on (d10) recording power conditions. Recording power condition (d10) may contain information indicating a recording pulse is greater than a recording power for another recording pulse corresponding to the front end of the recording mark.
