    Abstract: A recording method for an optical disk drive is implemented as follows. First, at least one of the level of the focusing error signal, the level of the tracking error signal, a wobble synchronization pattern loss, the error rate of demodulating a wobble signal, the frequency of buffer under-run occurrence, the temperature of the drive, the wobble jitter and the level of write power is detected. If at least one detected value exceeds the preset value, the recording will be ceased. Then, the rotation speed of the optical disk drive is decreased, and the recording is resumed with the decreased rotation speed. If at least one of the temperature of the drive, the wobble jitter and the estimated write power exceeds the reset value before recording starts, the rotation speed of the optical disk drive is decreased before recording.

    Abstract: An injection-locked frequency divider (ILFD) including a signal injector, an oscillator (OSC), and a buffer stage is provided. The signal injector is configured for receiving an injection signal. The OSC is configured for dividing the frequency of the injection signal, so as to generate a first divided frequency signal, where there is an integral-multiple relation between the frequency of the first divided frequency signal and that of the injection signal. The buffer stage is configured for receiving and boosting the first divided frequency signal, and performing a push-push process on the first divided frequency signal, so as to output a second divided frequency signal, where there is a fractional-multiple relation between the frequency of the second divided frequency signal and that of the injection signal.

The feedforward control circuit comprises a duplicate linear amplifier circuit and a hysteresis comparator. The duplicate linear amplifier circuit amplifies the input voltage signal, so as to output a reference voltage signal, wherein an amplifying gain of the duplicate linear amplifier circuit is identical to an amplifying gain of the linear amplifier circuit. The hysteresis comparator compares the output voltage signal and the reference voltage signal, so as to output the comparison signal.
