Abstract:
1. A magnetic disk device comprising: magnetic disks; magnetic head arms providing access to the magnetic disks; and wind shield members each arranged above or below said magnetic disks in a region adjacent to and on the rotationally upstream side of said magnetic head arms for restricting the impact of an air flow generated by the rotation of the magnetic disks against the magnetic head arms, said wind shield members having an entrance edge and an exit edge, said exit edge being downstream of said entrance edge in a rotational direction of said air flow, wherein said entrance edge has a curved guide surface, looking perpendicular to surfaces of said magnetic disks, for guiding the generated air flow to the outside of the magnetic disks, and wherein said entrance edge is concavely curved and is not parallel to said exit edge, which is convexly curved.
