Patent ID: 7414936

Claim:
An optical disk recording apparatus for optically recording data onto a recordable optical disk, said optical disk recording apparatus comprising: (A) a semiconductor laser for emitting laser light to said recordable optical disk at a predetermined power level; (B) a recording-speed setting section for setting a recording speed and producing an output as a set item of recording speed information; (C) a write strategy decoder which receives write strategy data from said recordable optical disk and decodes the write strategy data from said recordable optical disk into a write strategy, said write strategy data received by said write strategy decoder corresponding to said recording speed; (D) a recording-pattern-determination section for determining a recording pattern corresponding to target data of recording; (E) a recording-pulse-determination section for converting said recording pattern into a recording pulse according to said write strategy; (F) a recording-power-determination section for performing an optimum power calibration, thereby determining a recording power level of said semiconductor laser; and (G) a laser driver for driving said semiconductor laser according to said recording pulse and said recording power level.
