Patent number: 7348650Abstract: A method of manufacturing an element having a microstructure of an excellent grating groove pattern or the like is obtained. This method of manufacturing an element having a microstructure comprises steps of forming a metal layer on a substrate, forming a dot column of concave portions on the surface of the metal layer and anodically oxidizing the surface of the metal layer formed with the dot column of concave portions while opposing this surface to a cathode surface thereby forming a metal oxide film having a grating groove pattern. When the interval between the concave portions of the dot column is reduced, therefore, a linear grating groove pattern having a large depth with a uniform groove width along the depth direction is easily formed in a self-organized manner.Type: GrantFiled: October 10, 2006Date of Patent: March 25, 2008Assignee: Sanyo Electric Co., Ltd.Inventors: Kazushi Mori, Mitsuaki Matsumoto, Koji Tominaga, Atsushi Tajiri, Koutarou Furusawa

Publication number: 20080019254Abstract: A laser beam emitted from a light source is divided into a main beam and two sub-beams by a diffraction grating. A filter is arranged between a collimator lens and an objective lens. A filter unit is arranged in a predetermined pattern in the filter. The filter unit gives a maximum transmittance or a maximum reflectance at an incident angle at which the laser beam is incident in a parallel light state. The filter unit is formed in a pattern in which at least the laser beam reflected from a layer except a recording layer of an irradiation target is prevented from entering a sub-beam sensor pattern.Type: ApplicationFiled: July 20, 2007Publication date: January 24, 2008Applicant: Sanyo Electric Co., Ltd.Inventors: Kazushi Mori, Katsutoshi Hibino, Kenji Nagatomi, Naoyuki Takagi
