发明名称 METHOD FOR MANUFACTURING OPTICAL DISK MASTER, METHOD FOR MANUFACTURING OPTICAL DISK, AND APPARATUS FOR MANUFACTURING OPTICAL DISK MASTER
摘要 A method for manufacturing an optical disk master, a method for manufacturing an optical disk, and an apparatus for manufacturing an optical disk master are provided. The method for manufacturing an optical disk master includes measuring the reflectance of laser light at each of a plurality of radius positions by applying the laser light to an optical disk master-forming substrate provided with an inorganic resist layer, the laser light having a non-recording laser power smaller than a recording sensitivity of the inorganic resist layer, producing recording power control data indicating recording laser powers in accordance with the radius positions of the optical disk master-forming substrate by using the reflectances measured, forming an exposure pattern on the inorganic resist layer by applying the laser light to the optical disk master-forming substrate on the basis of the recording power control data while the recording power is varied in accordance with the radius positions, and developing the inorganic resist layer provided with the exposure pattern so as to prepare an uneven pattern.
