ABSTRACT:
In a dye-type optical recording medium, a write strategy for use in recording is determined based on recommended write strategy parameters recorded on an optical disk (160) and the characteristics of the optical recording device, and recording is carried out on the optical disk (160) according to the determined write strategy. In a medium of the phase change type, a power ratio and modulation degree for use in recording are determined from a recommended pulse width value in the recommended write strategy parameters recorded in the optical disk (160), the recommended power ratio value, the recommended recording power value, and the characteristics of the optical recording device, and recording is carried out on the optical disk (160) according to the power ratio value and modulation degree value thus determined. Optimal recording can be carried out even on an optical disk for which the optimal write strategy information has not been determined in advance, without the need to store write strategy information suitable for each and every optical disk.
