ABSTRACT:
An information recording method that obtains optimum recording conditions for recording multi-value data m on a recording medium includes recording a test pattern in a trial writing area of the recording medium by changing a recording power Pw and an erasing power Pe consecutively while maintaining a constant ratio between the recording power Pw and the erasing power Pe, and selecting the recording power Pw and the erasing power Pe producing reproduced results in which a reproduced signal level is substantially linear with respect to the multi-value data m, as an optimum recording power and an optimum erasing power, respectively.
