Abstract
According to one embodiment, a magnetic disk device of an embodiment includes a rotary shaft, a shroud, and a damper. The rotary shaft rotates the plurality of disks. The shroud surrounds at least a part of the disk along the outer edge of the disk with a space from the outer edge of the disk. The damper is provided on a downstream side of the shroud with respect to a flow between the disks induced by rotation of the disks, and the damper has a portion intersecting with the flow and a portion along the flow.
Claims8
A magnetic disk device comprising:
- a rotary shaft configured to rotate a plurality of disks,
- a shroud that surrounds at least a portion of the disk along an outer edge of the disk with a gap between the shroud and the outer edge of the disk;
- and
- a damper that is fixed to the device and provided on a downstream side of the shroud with respect to a flow between the disks induced by rotation of the disks, and has a portion intersecting the flow and a portion along the flow,
- wherein the damper is a one-piece damper having a first arm portion and a second arm portion, the first arm portion is a portion of the damper intersecting the flow, and the second arm portion is a portion of the damper facing from a downstream side to an upstream side of the flow,
- wherein the first arm portion and the second arm portion are connected by a portion of the damper having a curved shape.
