Abstract
A method for optimizing write parameters using two-stage adjustment is provided. A first kind of write strategy parameters optimization procedure for adjusting at least one static write strategy parameter of a write strategy is performed. A second kind of write strategy parameters optimization procedure for adjusting at least one dynamic write strategy parameter of the write strategy is performed after performing the first kind of write strategy parameters optimization procedure. The static write strategy parameter corresponds to a signal length of a pit on an optical disk and the dynamic write strategy parameter is utilized to overcome heat interference when forming the pit.
