The invention provides a disc device capable of preventing lubricant from polluting the inside. A disk device according to one embodiment includes a magnetic disk and a rotating unit. The magnetic disk has a recording surface facing a first direction, and is rotatable about a first rotation axis extending in the first direction. The rotating unit includes a rotating member, a bearing, and a first filter. The bearing supports the rotating member so as to be rotatable about a second rotation axis extending in the first direction, and contains a lubricant. The first filter is capable of collecting the lubricant. The rotating member is provided with a housing hole extending along the second rotating shaft and housing the bearing, and a first communication port extending in a direction intersecting the second rotating shaft and communicating the housing hole with the outside of the rotating member. The first filter is provided to the first communication port or covers the first communication port. 本发明提供能够抑制润滑剂污染内部
