摘要： A fan module and server equipment are provided that can achieve a balance between increased airflow and noise reduction when an axial flow fan is mounted in the server equipment.The fan module for taking in and discharging air includes a stator located on an upstream side with respect to airflow and an axial flow fan located on the downstream side. When the fan module is viewed from the rotational-axial direction of the axial flow fan, if a leading edge of a rotor vane constituting part of the axial flow fan passes a trailing edge of a stator vane constituting part of the rotor, a skew is formed in which the leading edge of the rotor vane constantly intersects the leading edge of the rotor vane at a single point.

摘要： Since the surface roughness of a recording layer get larger in the process of fabricating a patterned medium, the spacing between a head and the medium is widened. As a result, the recording performance and corrosion resistance of the medium are degraded. In the patterned medium, a recording layer includes one layer of a crystalline magnetic film or plural layers of crystalline magnetic films, and a magnetic film of an amorphous structure located on the outermost surface of the crystalline magnetic films. The compositional elements of the magnetic film of the amorphous structure are identical to those of the crystalline magnetic film located immediately under the magnetic film. In a fabrication method thereof, the surface of the crystalline magnetic film is turned into amorphous in order to form the magnetic film of the amorphous structure.
