A method is provided to start calibrating TE signals in an optical disk drive by checking the change of focus balance, outputting a first TE signal by adjust to a predetermined gain, measuring the peak and trough of the first TE signal, changing the laser power to output a second TE signal on condition of the same focus balance and predetermined, measuring the peak and trough of the second TE signal, calculating and adjusting to a calibrated gain to quickly calibrate the TE signal. |
