METHOD OF MEASURING CHARACTERISTIC DATA RELATING TO MULTILEVEL OPTICAL RECORDING MEDIUM AND EVALUATION METHOD RELATING TO MULTILEVEL OPTICAL RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a method of measuring the character data relating to a multilevel optical recording medium capable of reducing a measuring cost. ;SOLUTION: The measuring method of measuring the characteristic data relating to the multilevel optical recording medium manufactured in such a manner that multilevel recording is possible comprises measuring the characteristic data relating to the multilevel optical recording medium by using an apparatus for evaluating binary recording and reproducing (steps 31 to 33). As a result, the characteristic data relating to the multilevel optical recording medium can be measured without freshly purchasing or manufacturing an apparatus for evaluating multilevel recording and reproducing to be exclusively used and therefore the measuring cost thereof can be reduced.;COPYRIGHT: (C)2003,JPO
