ABSTRACT:
A DVD-R recorder according to the invention detects an item of recording speed information (d15) from a DVD-R (30) on which histories of recording speed information, write strategy, and recording power condition are stored. When the decoded item of recording speed information (d15) agrees with a set item of recording speed information (d17), the recorder detects the write strategy (d6) and the recording power condition (d10) corresponding to the decoded item of recording speed information (d15). A recording-pulse-determination section (9) converts a recording pattern (d8) into a recording pulse (d9) according to the write strategy (d6). A recording-power-determination section (12) performs an OPC based on the recording power condition (d10). The recording power condition (d10) may include information specifying that a recording pulse corresponding to the front edge of a recorded mark has a larger recording power than other recording pulses.
