Silane coupling agents which are high in heat resistance, and which are high in durability, releasability, and antifouling properties. When light is irradiated to a region including the first inspection pattern and the second inspection pattern and a spectrum is formed based on the reflected diffracted light, information of a line width of the second inspection pattern and a pitch of both inspection patterns is contained therein. In one embodiment, a first attribute is selected from metadata associated with a media data file and an attribute dependency corresponding to the first attribute is determined.
