摘要： Ultra smooth as-deposited composite nickel coatings for use in an information storage system are provided. The composite nickel coatings include an electrolessly deposited nickel layer formed on a sputter deposited nickel layer. The composite nickel coatings have an as-deposited surface roughness of less than about 10 Å. Embodiments include formation of the composite nickel coating on a disk, followed by deposition of an underlayer and magnetic layer thereon to form a magnetic recording medium.

摘要： Surface processing of metal, such as CMP, is enhanced and defects reduced by pretreatment to remove a surface layer exhibiting properties different from the bulk metal, such as a baked on oxide layer. Embodiments of the present invention include acid soaking a non-magnetic substrate having an Al, Ni or Ni—P surface with a baked oxide film thereon, thereby removing the oxide film and rendering the reduced surface amenable to CMP with reduced defects, reduced surface roughness and increased production throughput.

摘要： Magnetic recording media including an alternative substrate material having a Young's Modulus greater than that of Al-based substrate materials and a preselected average surface roughness (Ra) are formed by depositing a continuous, adherent, non-magnetic, catalytically active layer on a surface of the substrate and electrolessly plating an amorphous seed layer on the catalytically active layer, the Ra of the resultant surface of the amorphous seed layer being reduced from that of the substrate, thereby providing a substantially defect-free surface for deposition thereon of magnetic recording media layers thereon. Embodiments include sputter depositing an catalytically active layer of Ni—Al or Ni—P and electrolessly plating an amorphous seed layer of Ni—P thereon.

摘要： A corrosion-resistant granular magnetic recording medium with improved recording performance comprises a non-magnetic substrate having a surface; and a layer stack on the substrate surface, including, in order from the surface: a granular magnetic recording layer; an intermediate magnetic de-coupling layer; and a corrosion preventing magnetic cap layer. The intermediate magnetic de-coupling layer has an optimal thickness and/or composition for: (1) promoting magnetic exchange de-coupling between the granular magnetic recording layer and the magnetic cap layer; and (2) reducing the dynamic closure field (Hcl) for determining writeability and eraseability of the medium. Grain boundaries of the magnetic cap layer are substantially oxide-free, and have a greater density and lower average porosity and surface roughness than those of the granular magnetic recording layer.
