    • A recording power determination method for determining a recording power of an optical beam for recording data on an information storage medium includes the steps of recording test data on the information storage medium at a plurality of test recording powers; reading the test data recorded at each test recording power, generating a signal, and measuring a modulation factor of the signal corresponding to each test recording power; calculating a product of an n'th power of each test recording power and the corresponding modulation factor, thereby obtaining a plurality of products corresponding to the plurality of test recording powers, where n is a value of exponent and is a real number other than 1; calculating a first recording power based on the correlation between the plurality of test recording powers and the plurality of products; and calculating the recording power based on the first recording power.
    • 用于确定用于在信息存储介质上记录数据的光束的记录功率的记录功率确定方法包括以多个测试记录功率将测试数据记录在信息存储介质上的步骤; 读取在每个测试记录功率下记录的测试数据,产生信号,并测量与每个测试记录功率对应的信号的调制因子; 计算每个测试记录功率的第n次功率的乘积和相应的调制因子,由此获得与多个测试记录功率对应的多个产品,其中n是指数值,并且是除1之外的实数 ; 基于所述多个测试记录功率与所述多个产品之间的相关性来计算第一记录功率; 以及基于第一记录功率计算记录功率。
