Abstract:
1. An optical disk device for driving an optical disk having a rotation center and a recording track around the rotation center, the device comprising: a light source for emitting a light beam; an objective lens for irradiating a position on the recording track of the optical disk with the light beam from the light source; a lens holding member holding the objective lens, the lens holding member having a plurality of fitting sections; a plurality of elastic supporting members each having a longitudinal length and fitted at one end thereof to one of the fitting sections of the lens holding member; and a supporting unit base having a plurality of anchor sections supporting the other end of each of the elastic supporting members, wherein the plurality of anchor sections are arranged on first and second sides with reference to a tangent line hypothetically drawn tangentially to the recording track at the position irradiated with the light beam via the objective lens, the rotation center of the optical disk being located on the second side, and wherein each of the anchor sections that are arranged on the first side are arranged closer to the objective lens in the extending direction of the tangent line than are the anchor sections arranged on the second side.
