<P>PROBLEM TO BE SOLVED: To restrain manufacture of an information recording medium of an insufficient display quality. <P>SOLUTION: The manufacturing apparatus 50 of the information recording medium is equipped with a printing part 510 which forms a printing pattern on a base material 10', and a laser machining part 520 which forms a black pattern by laser beam machining of the base material 10' with the printing pattern formed thereon. The laser machining part 520 includes a support 5201 which supports the base material 10' with the printing pattern formed thereon, a laser drawing device 5204 which draws a black pattern by laser beam irradiation of the base material 10' supported by the support 5201, an illuminating device 5202 which illuminates the base material 10' supported by the support 5201 with visible light and/or invisible light, an image capturing device 5203 which outputs image information by photographing the base material 10' supported by the support 5201 and illuminated with the visible light or invisible light, and a control part 560 which controls the drawing action of the laser drawing device 5204 utilizing the image information. <P>COPYRIGHT: (C)2009,JPO&INPIT |
