A write adjustment method adjusts recording power, recording time, and recording position of a recorder. The recorder includes a light detecting chip to receive a reflected light signal and generate a recording detection signal to a high pass filter. The high pass filter receives the recording detection signal and outputs a filtering signal. The write adjustment method includes writing first short period data to a disk, acquiring a reference voltage of the high pass filter according to a maximum value and a minimum value of the filtering signal, writing first mixing period data to the disk according to a plurality of predetermined recording times, acquiring a first maximum value and a first minimum value according to the filtering signal and adjusting and determining a first recording power of the recorder when a target value is achieved according to the first maximum value, the first minimum value and the reference voltage of the high pass filter.
