Abstract
A method for determining an optimum write power for writing data to an optical disc is disclosed. The method includes utilizing a plurality of candidate write powers for writing data to the optical disc; measuring at least a writing quality parameter corresponding to each of the candidate write powers, respectively; determining a characteristic curve of the writing quality parameters to the candidate write powers; and determining the optimum write power according to a write power corresponding to a target inflection point of the characteristic curve.
