本申请记载了一种光学记录方法和使用这种方法的记录装置，其中在该装置中辐射束的最佳写入功率是通过以下步骤设定的，在一个光学可记录媒体上写入一组测试图案，根据这些图案产生一个读取信号，从媒体上读取读取信号相对于写入功率调制的导数的一个预定值，处理读取信号和预定值以求得写入功率的最佳值。 An optical recording method and recording apparatus using this method is described in which an optimum write power of a radiation beam in the apparatus is set by writing a series of test patterns on an optical recordable medium, forming a read signal from the patterns, reading a preset value of the derivative of the modulation of the read signal with respect to the write power from the medium, and processing the read signal together with the preset value to derive an optimum value of the write power.
