In an optical recording method, recording parameters (WU) to be used for recording are obtained using recommended recording parameter values (WR) read from an optical recording medium and previously obtained vector information (PC) and approximation coefficients (Ca, Cb) (S24). Writing to the optical recording medium is performed using the obtained recording parameters (S17). The vector information (PC) includes a vector component of the parameters obtained statistically with respect to parameter difference values (DF) between optimal recording parameter values (WO) and the recommended recording parameter values (WR) over a plurality of optical recording media so as to strengthen mutual correlation between the parameters. The approximation coefficients (Ca, Cb) are obtained by approximating a relationship between converted information (X) and feature information (D), the converted information (X) indicating a relationship between the vector information (PC) and the parameter difference values (DF), the feature information (D) indicating the features of each optical recording medium obtained from the recommended recording parameter values (WR) and the vector information (PC). |
