摘要：
An information recording method includes the steps of recording test data with changing a top pulse width Ton and monitoring reflected light intensity; determining an optimum top pulse width from the monitoring result; determining respective optimum off pulse widths according to multilevel data from a monitoring result of the determined optimum top pulse width; recording test data with changing recording power in sequence with the use of the optimum top pulse width and the optimum off pulse width determined, monitoring reflected light intensity, and thus determining optimum recording power.
