Abstract
A disk device according to one embodiment includes a base, a first cover, a second cover, and a damper. The base includes a bottom surface, a side wall protruding in a first direction from the bottom surface, and a support surface located at an end of the side wall in the first direction. The first cover is attached to the base to close the inner space. The second cover is joined to the base while being supported by the support surface, to cover the first cover. The damper includes a constrained layer in-between the first cover and the second cover and a viscoelastic material between the first cover and the constrained layer. The constrained layer includes a smaller-thickness part extending along the support surface and a larger-thickness part connected to the smaller-thickness part.
