Abstract
According to one embodiment, a disk device includes a housing including a bottom wall including a protrusion with a first surface, a recording medium arranged in the housing, a printed circuit board attached to the bottom wall, an electronic component mounted on the printed circuit board and including a second surface facing the first surface, and a radiation sheet including a third surface which is contact with the first surface, and a fourth surface which is in contact with the second surface. An area of the first surface is less than an area of the third surface of the radiation sheet, or an area of the second surface is less than an area of the fourth surface of the radiation sheet.
Claims7
A disk device comprising:
- a housing comprising a bottom wall comprising an outer surface and a protrusion provided on the outer surface and having a first surface;
- a recording medium arranged in the housing;
- a printed circuit board attached to the bottom wall to oppose the outer surface of the bottom wall;
- an electronic component mounted on the printed circuit board and having a second surface facing the first surface;
- and
- a radiation sheet provided between the first surface and the second surface and having a third surface which is in contact with the first surface and apart from the outer surface of the bottom wall, and a fourth surface which is opposite to the third surface, in contact with the second surface, and apart from the printed circuit board, wherein
- an area of the first surface is less than an area of the third surface of the radiation sheet and is less than an area of the second surface, and the first surface compresses the radiation sheet, or an area of the second surface is less than an area of the fourth surface of the radiation sheet and is less than an area of the third surface, and the second surface compresses the radiation sheet.
A disk device comprising:
- a housing comprising a bottom wall comprising a contact portion having a first surface;
- a recording medium arranged in the housing;
- a printed circuit board facing the bottom wall and attached to the bottom wall;
- an electronic component mounted on the printed circuit board and having a second surface facing the first surface;
- and
- a radiation sheet arranged between the first surface and the second surface and being in contact with the first surface and the second surface, wherein
- one of the first and second surfaces has an area less than an area of the radiation sheet, is entirely in contact with the radiation sheet and compresses the radiation sheet.
