Abstract: According to one embodiment, a disk device includes an open-topped, plate-like base, a plate-like top cover which is attached to the base and closes a top opening, a printed circuit board provided opposite the base on the reverse side thereof, and a plate-like bottom cover which covers the reverse side of the printed circuit board and the base. Provided on the base are a disk-shaped recording medium and a mechanical section which includes a head for processing information on the recording medium, a head actuator supporting the head, and a drive motor which supports and rotates the recording medium. The printed circuit board has a projection and an electronic component mounted in the notch portion by being at least partially dropped therein. The base has projections which project on the printed circuit board side and engage and support the electronic component.
