An optical disk apparatus includes a detector (PU) for detecting a data string corresponding to a waveform pattern having a predetermined time width, an ideal signal generator (16) for generating a data string of an ideal signal having a predetermined time width, which corresponds to a data string having the predetermined time width, a parameter calculator (19) for comparing the detected data string with the data string of the generated ideal signal, and determining a waveform compensation amount (C) on the basis of the comparison result, a recording waveform generator (11) for generating a recording waveform pulse (P) on the basis of externally supplied recording data (R) and the waveform compensation amount (C), and a pickup (PU) for irradiating a storage area of the optical disk with a laser beam in accordance with the recording waveform pulse (P) to record the recording data. |
