<p>In a disc device (100), a reinforcing section (310) is arranged at a downstream opening end (302A) positioned in the downstream in the rotating direction of an optical disc, on a processing opening section (301) which corresponds to a shift path of an information processing section (240) of a TM cover member (300) of a traverse mechanism (200). The reinforcing section (310) is formed as a step having a step section (311) on a side separated from the optical disc. Strength against a warping force of the TM cover member (300) is improved by a negative pressure status generated by high-speed rotation of the optical disc. An air flow toward the optical disc is generated by the step section (311), and warping is eliminated. A contact with the optical disc due to warping is eliminated.</p> |
