<P>PROBLEM TO BE SOLVED: To provide a recording method and an optical disk device with which write preparation time can be remarkably shortened. <P>SOLUTION: A recording power adjustment process to adjust recording power is carried out in each recording layer of a multilayered optical disk, and a shift test writing process to adjust the pulse condition of a recording pulse is carried out only with regard to a part of recording layers out of respective recording layers. Then, on the basis of the processing result of the recording power adjustment process and the processing result of the shift test writing process, the 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 disk while adjusting the pulse condition of the recording pulse on the basis of the processing result of the shift test writing process or the prediction result. <P>COPYRIGHT: (C)2009,JPO&INPIT |
