PROBLEM TO BE SOLVED: To improve grade of recording signal by decreasing jitters, etc. SOLUTION: A timing for starting the irradiation of the laser beam of a recording power for forming the following pit is corrected according to the next pit length. Namely, the longer the next pit is, the more the timing to start emitting the laser beam for the recording power is delayed. Moreover, the timing for finishing the irradiation of the laser beam of the recording power for forming the previous pit is corrected according to the next land length. Namely, the shorter the next land length becomes, the more the timing for finishing irradiation of the laser beam of the recording power is advanced. |
