Title: Method for manufacturing perpendicular magnetic recording disk
Inventor: MARINERO ERNESTO E
IPC: G11B5/851
Filed: 2007-02-14
Abstract: <P>PROBLEM TO BE SOLVED: To give good corrosion resistance without degrading recording performance, in a perpendicular magnetic recording disk provided with a recording layer (RL) added with an oxide into a granular cobalt alloy.  <P>SOLUTION: An intermediate layer (IL) having a hexagonal close packing (hcp) crystal structure, and made from Ru or Ru alloy, is vapor-deposited in a sputter pressure substantially lower than before, so that a columnar structure of the intermediate layer decreases more than before, and a surface of the intermediate layer becomes smoother than before. The comparatively smooth surface of the intermediate layer (IL) so obtained is denaturalized by irradiation with ion, such as sputter etching in an argon ambient atmosphere, to form surface roughness in a nano-scale and to grow the recording layer (RL) on it. Thus, when the surface of the intermediate layer (IL) is made into a roughened surface, in the case of growing the recording layer (RL), grain isolation in the recording layer is promoted, but since the intermediate layer (IL) has little columnar structures, paths of water or corrosive decrease more than before.  <P>COPYRIGHT: (C)2007,JPO&INPIT

In this manner, the Mg atomic layer having a thickness of the order of one atomic layer can be formed. After that, continuously in the same MOCVD apparatus, a second semiconductor crystal layer 5 formed of GaN is grown on the Mg atomic layer while maintaining the same temperature (1,100°C). First, the second semiconductor crystal layer 5 starts three-dimensional growth from growing nuclei scattered around the upper exposed surface of the Mg atomic layer into island shapes, then the islands are grown, contact with one another and coalesce. After that, a growth mode is naturally shifted to a general two-dimensional growth mode under the same crystal growth conditions. In this manner, the density of generation of threading dislocation 5a can be efficiently reduced.  <P>COPYRIGHT: (C)2008,JPO&INPIT
