PROBLEM TO BE SOLVED: To prevent data from being wrongly transmitted. SOLUTION: A micro computer 9 transmits waveform data which shape the wave-forms of laser drive signals to an ALPC unit built in a pickup unit 3. The micro computer 9 acquires data transmitted from the ALPC unit and compares the transmitted data with the acquired data. As a result of comparison, when two data are different from one another, the micro computer 9 controls to decelerate a data transfer rate. |
