Optical disk device including a support member for movably supporting an
objective lens in focusing and radial directions with respect to an
optical disk
摘要:
An optical disk device includes a light source, an objective lens, a box body and a supporting member. The light source is provided so as not to move to the apparatus body. The box body holds the objective lens. The box body is supported movably to the apparatus body in the tracking, focusing and seek directions by the supporting member. A light beam emitted from the light source is guided to the objective lens by the mirror.
