摘要 |
When manufacturing a recording medium, a material layer 12 formed on a substrate 11 that composes the recording medium is exposed to a laser beam in accordance with a recording pattern. The material layer 12 has a predetermined reflectivity for the laser beam 13 so as to produce return light for the laser beam 13. By detecting this return light, the focusing of the laser beam on the material layer is adjusted. By doing so, a laser beam can be easily and accurately focused on a material layer during a process in which a laser beam is shone, in accordance with a recording pattern, onto a material layer formed on a recording medium or a production plate used when manufacturing a recording medium.
