Method for calibrating a spherical aberration compensation level in an optical drive
Abstract:
A method for calibrating an SA compensation level of an optical drive is provided. The method includes steps of providing a plurality of SA compensation levels; obtaining a peak-to-peak value of an S curve corresponding to each of the SA compensation levels; selecting a maximum of the peak-to-peak values of the S curves and the SA compensation level corresponding to the maximum; and setting the selected SA compensation level to be an optimal SA compensation level.
