Abstract
Embodiments of the invention provide a disk drive suppressing a surface deformation of a top cover. In one embodiment, the disk drive includes a base and a top cover. The base accommodates a head assembly, a circuit unit, and a recording medium. The top cover is supported by the base at a plurality of inner points of support and peripheral edge points of support on a peripheral edge portion near a portion accommodating the head assembly and the circuit unit. The top cover covers the accommodating portion of the base. A vibration suppression member for suppressing vibration of the top cover is disposed in a polygon. The polygon has, as vertices, a plurality of inner points of support and, among the peripheral edge points of support, the peripheral edge points of support near the portion accommodating the head assembly and the circuit unit. The vibration suppression member is disposed at a position in the polygonal portion corresponding to an area near a loop of vibration in a surface of the top cover.
