摘要: The device seeks to improve the reliability of information and increase recording capacity by controlling mark be recorded on medium with high preciseness. To conformity a that records, retrieves erases information, pulse train is generated test write data generating circuit 18 forming 15 5 laser driver 14. Excessive power reduced, an optimum determined regular retrieving carried out detecting from 12 which retrieved signal input. Based upon analysis controller 19, range next scan changed so as avoid excessive while making it possible determine power.
