The present invention automatically performs a series of measurements on an optical media based on writing a power ramp signal of known power levels (amplitudes) on a target sector of the optical media. The amplitudes of the written power levels are measured. A comparison of the measured amplitude of...http://www.google.com/patents/US5050156?utm_source=gb-gplus-sharePatent US5050156 - Method and apparatus for calibrating the writing power applied to an optical media
