Abstract: The invention provides a wobble detection circuit. An exemplary embodiment of the wobble detection circuit comprises an automatic gain control module, an analog to digital converter, a digital band pass filter, and a digital band pass filter. The automatic gain control module amplifies a first input signal and a second input signal detected by a pickup head to the same magnitude to obtain a first amplified signal and a second amplified signal. The adder then subtracts the second amplified signal from the first amplified signal to obtain an analog wobble signal. The analog to digital converter then converts the analog wobble signal to a first digital wobble signal. Finally, the digital band pass filter accepts frequency components of the first digital wobble signal within a pass band and rejects frequency components of the first digital wobble signal outside the pass band to obtain a second digital wobble signal.

Abstract: 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.

Abstract: A device for processing a radio frequency (RF) signal of an optical disk drive includes a high-pass (HP) filter, an RF variable gain amplifier (VGA), an RF analog-digital converter (ADC), and a digital module. The HP filter filters the RF signal and is capable of selectively utilizing one of a first cut-off frequency and a second cut-off frequency. The RF VGA amplifies the filtered RF signal. The RF ADC converts the amplified RF signal into a digital code. The digital module is capable of executing a first function and a second function with the digital code. The HP filter utilizes the first cut-off frequency when the digital module desires to execute the first function, and the HP filter utilizes the second cut-off frequency when the digital module desires to execute the second function.
