INFORMATION RECORDING METHOD TO OPTICAL RECORDING MEDIUM, INFORMATION RECORDING DEVICE, OPTICAL RECORDING MEDIUM AND EVALUATION METHOD FOR OPTICAL RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide such an information recording method to an optical recording medium that jitter of new data can be reduced, when the new data are overwritten directly on data after the lapse of a long time since recorded on the optical recording medium. SOLUTION: When recording is carried out by using each of a plurality of combination of recording power and erasing power, while fixing the ratio of recording power and erasing power of a laser beam, such an intermediate value between the lower limit and the upper limit of recording power that jitter becomes 10% or less is defined as Pw0. When recording is performed by using each of a plurality of erasing power, while fixing recording power to Pw0, such an intermediate value between a lower limit and an upper limit of erasing power that jitter becomes 10% or less is defined as Pe0. Information is recorded by setting the recording power of the laser beam to Pw0 and the erasing power to a power beyond Pe0.
