摘要： The present invention sets forth a power saving method and a power saving system applied in an optical disk drive. The power saving system comprises a central processing unit, a spindle motor, an optical pick-up unit, an analog portion of control circuits and a digital portion of control circuits. Each of the analog or digital portions of control circuits can be divided into several sets of circuits. Each set of circuits is coupled to an associated operation mode of the optical disk drive. The power saving system further comprises a power controlling unit for differentiating the specific sets of circuits not being used in the specific operation mode and powering them down. The sets of circuits not being used will be powered up while the associated operation mode in which they are required to operate is nearly started. The present invention also provides a power saving method of powering down the sets of circuits not being used relative to a specific operation mode of the optical disk drive.

摘要： An apparatus and a method for compensating periodic signal in an optical disc drive are described. The control apparatus includes an amplitude processing unit, a phase processing unit, a wave generator, a first switch module and a second switch module. The amplitude processing unit processes the amplitude of the input signal based on a reference signal for generating an amplitude signal. The phase processing unit processes the phase of the input signal based on the reference signal for generating a phase signal. The first switch module switches the amplitude signal to select one of the amplitude value and a predetermined amplitude value. The second switch module switches the phase signal to select one of the phase value and a predetermined phase value. The wave generator generates a compensated wave signal based on the selected amplitude value and the selected phase value, and outputs the compensated wave signal.

摘要： An apparatus and a method for compensating periodic signal in an optical disc drive are described. 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).
