ABSTRACT:
A recording power adjustment process to adjust a recording power is carried out in each recording layer of a multilayered optical disc, and a shift test writing process to adjust the pulse condition of a recording pulse is carried out only with regard to some of the respective recording layers. Then, based on the processing result of the recording power adjustment process and the processing result of the shift test writing process, a processing result of the shift test writing process in each of the recording layers, to which the shift test writing process has not been performed, is predicted. Then, information is recorded on a corresponding recording layer of the multilayered optical disc while adjusting the pulse condition of the recording pulse based on the processing result of the shift test writing process or the prediction result.
