摘要:
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.
