Abstract
A magnetic disk device includes a disk rotatable in a rotation direction and a shroud that at least partially surrounds the disk along an outer edge of the disk with a gap from the outer edge of the disk. A guide vane is connected to the shroud at a downstream side of an airflow generated in the rotation direction. The guide vane has a structure that decelerates an airflow between the guide vane and the disk.
