Method of forming micropattern, method of manufacturing optical recording medium master copy, optical recording medium master copy, optical recording medium stamper, and optical recording medium |
| abstract |
By using an existing, relatively inexpensive manufacturing device, micropatterns (e.g. guiding grooves, prepits) having such track pitch and pit pitch that are smaller than the diameter of a light spot are formed more finely. There are provided at least two layers, i.e. (i) a resin substrate and (ii) a depressed part inducing layer made of dielectric material or metal oxide. A light beam is radiated and focused onto the depressed part inducing layer so as to form pit parts and/or guiding grooves on irradiated parts of the resin substrate. The depressed part inducing layer is then removed, so as to expose the pit parts and/or guiding grooves. |
