Abstract:
A method for determining a bias voltage of a servo signal of an optical disc drive is disclosed. The method includes: generating a plurality of sensing signals via an optical sensor of the optical disc drive; generating a first and a second servo signals according to the sensing signals; adjusting the first and the second servo signals to generate a first and a second adjusted signal respectively; and determining the bias voltage of the servo signal according to the first and the second adjusted signals.
