<P>PROBLEM TO BE SOLVED: To provide an effective method for inspecting recording quality decided by a combination of drives and media. <P>SOLUTION: A reference medium 18 as a quality standard for each kind of medium is recorded and reproduced for each of the drives 20-1 to 20-5, and threshold values 1 to 5 obtained by multiplying the characteristic values obtained as the results by predetermined coefficients, respectively, are stored in predetermined respective storage areas prepared in each drive. When recording information in a medium for a recording object, the medium is recorded/reproduced by using a plurality of recording conditions accompanied by variation in power or a pulse width, and an approximate curve is calculated from the plurality of characteristics values obtained as a result, and the inspection of the recording quality to the medium is carried out based on a margin determined from a positional relation between the approximate curve and the threshold values. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
