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： A compensation method for detecting the seeking speed of an optical disk drive involves the following steps. First, a TE signal is converted into a TEZC signal, or an RFRP signal is converted into an RFZC signal. Then, take the average of the respective pulse widths of an upper waveform and an adjoining lower waveform of the TEZC signal or the RFZC signal to acquire the recovered TEZC signal or RFZC signal wherein both the upper waveform and the lower waveform are decided by a slice levels.

The first data layer corresponds to a first SAC value, while the second data layer corresponds to a second SAC value. A processor of the optical data accessing apparatus is adapted for: (1) generating and sending a focus off signal to a pickup control unit to disable focus control; (2) generating a target value for an SAC to adjust an SAC value from the first SAC value to the target value, wherein the target value is between the first SAC value and the second SAC value; and (3) generating and sending a focus activation signal to the pickup control unit to re-enable the focus control to focus on the second data layer while the SAC value reaches the target value.
