摘要： The invention provides an apparatus for controlling servo signal gains of an optical disc drive. The apparatus adjusts the gains of a plurality of servo signals controlling a servo system of the optical disc drive when the optical disk drive encounters an operating state transition. In a first mode, at least one AGC loop of the apparatus compensates the gains of the servo signals with a selectable bandwidth during a specific period after the operating state transition to accelerate the convergence of the servo signals. In a second mode, at least one AGC loop of the apparatus reloads the previously saved convergence values or pre-determined values as the initial values according to the current operating state immediately after the operating state transition to accelerate the convergence of the servo signals.

The control apparatus includes an amplitude processing unit, a phase processing unit, and a wave generator. The amplitude processing unit processes the amplitude of the input signal (Sin) based on a reference signal (Sref) for generating an amplitude signal (Sad) wherein the amplitude signal (Sad) has at least one amplitude value (Vad). The phase processing unit processes the phase of the input signal (Sin) based on the reference signal (Sref) for generating a phase signal (Spd) wherein the phase signal (Spd) has at least one phase value (Vpd) during the cycle of the reference signal (Sref). The wave generator generates a compensated wave signal (Scom) based on the amplitude value (Vad) and the phase value (Vpd) during the cycle of the reference signal (Sref), and the wave generator outputs the compensated wave signal (Scom) for compensating the periodic signal of the input signal (Sin).
