One object is to facilitate maintenance of an inspection apparatus for an optical recording disk. In accordance with one aspect, the present method includes: determining whether an inspection apparatus for inspecting recording conditions of an optical recording disk can be further used based on a divergence index correlated to divergence from a state where the inspection apparatus is calibrated or on a difference between the divergence index and a reference value of the divergence index; and, if it is determined that the inspection apparatus can be further used, setting authorization for inspecting the optical recording disk by the inspection apparatus. This method enables inspection of optical recording disks with ensured inspection performance of the inspection apparatus.
