Abstract: A phase modulation method with a polar transmitter. A target frequency is first designated by comparing the RF signal with a reference frequency and the phase sample. An oscillator control word is generated based on the target frequency. A digital oscillator can modulate from a first phase to a second phase to synthesize a preliminary RF signal based on the oscillator control word. When the target frequency exceeds the modulation capability of the digital oscillator, the oscillator control word is generated based on the target frequency minus 180 degrees, and the preliminary RF signal is shifted by 180 degrees to be the RF signal having the target frequency. When the target frequency does not exceed the modulation capability of the digital oscillator, the oscillator control word is generated solely based on the target frequency to output the preliminary RF signal to be the RF signal having the target frequency.

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.
