Abstract
An optical disk device of the present invention includes an optical pickup which performs at least recording or reproduction of signals on or from an optical disk; a guiding section which supports and guides the optical pickup along the radial direction of the optical disk; an upper cover which protects the guiding section; a lower cover which protects the guiding section; and a base which supports the guiding sections therein. A height between the upper cover and the lower cover adjacent to an outer periphery of the optical disk is greater than a height between the upper cover and the lower cover adjacent to an inner periphery of the optical disk.
