Abstract
According to one embodiment, a case of a disk device includes a plate-shaped base formed of a non-magnetic material and having an open upper surface, and a plate-shaped top cover formed of a non-magnetic material and attached to the base to cover the open upper surface of the base. An outer surface of the base is covered with a first plating layer formed of a magnetic material, and an outer surface of the top cover is covered with a second plating layer formed of a magnetic material. The first and second plating layers are conductively connected to each other. A disk-shaped recording medium and a mechanical unit are arranged in the case. The medium has a substrate, a soft magnetic backing layer formed on the substrate, and a magnetic recording layer formed so as to overlap the soft magnetic backing layer and having perpendicular magnetic anisotropy.
