OPTICAL RECORDING METHOD, EVALUATION INDEX ACQUIRING METHOD, OPTICAL RECORDING DEVICE, MICRO CPU ELEMENT, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an optical recording method that can record information in a short period by reducing the test time before recording, an evaluation index acquiring method, an optical recording device, a one-chip CPU element, and a computer program therefor.;SOLUTION: This method records and reproduces the test information making changes of the kinds of recording conditions on a first recording layer 11 and finds out the light radiating conditions suitable to record information on the first recording layer 11. Then, it records and reproduces the test information on second and third recording layers 12, 13 by changing the kinds of recording conditions by less times than in the recording on the first recording layer and finds out the light radiating conditions suitable to record information on the second and third recording layers 12, 13, based on the result of the test for the first recording layer 11 and the result of the test for the second or third recording layer 12, 13. Thus, it can reduce the test time to find the light radiating conditions for the second and third recording layers 12, 13.;COPYRIGHT: (C)2007,JPO&INPIT
