An optical disk device is capable of reducing a thickness of a loading portion equipped with plural sheets of trays. Trays installed in a main body are energized to put an optical disk between them in the thickness direction. Therefore, a thickness of plural sheets of trays can be reduced by cutting down a clearance between the tray and the optical disk. Also, plural sheets of trays are energized by spring members to be put elastically between them in the thickness direction. Therefore, an excessive pushing force is not applied to the optical disk loaded on the tray. Also, a hollow portion of the tray is formed such that projection portions protruded in excess of a standard thickness dimension of the optical disk do not interfere with the tray. Therefore, even when the projection portions are protruded from an adapter, such adapter can be loaded on the tray.
