PURPOSE: An optical disk apparatus and a method for adjusting laser power of the same are provided to maintain the power irradiated on an active layer at an optimum laser power. CONSTITUTION: An optical disk apparatus(10), irradiating an active layer of an optical disk, with a laser, comprises a detection unit for detecting an amount of change in a factor causing fluctuation in effective power; a storage unit for storing compensation data indicating a relationship between an amount of change in the factor causing fluctuation in effective power and an optimum emitted power corresponding to the amount of that change; and a control unit for adjusting emitted power based on the compensation data and a value detected by the detection unit. The optical disk further comprises an acquisition unit for acquiring compensation correction values for correcting the compensation data from an optical disk on which recording is to be carried out. The control unit adjusts emitted power based on the detected value, the compensation data, and the compensation correction values.
