Abstract
The present invention provides a method and system for calibration of writing to an optical medium. The method includes: sampling marks in a calibration area of the optical medium; and converting the sampled marks into a digital format utilizing an ADC, the ADC also utilized by a servo control. The present invention provides a controller with an integrated servo and recording processor which allows a single ADC to be used for converting sample marks used in calibrating the writing to an optical media. No separate subsystem for converting sample marks is thus necessary. Less components are required, reducing the cost of manufacturing the controller. With less components, the risk of component failure is reduced as well.
