Abstract:

High areal density magnetic recording media exhibiting low noise are formed with a NiâPâX plating layer, in which X is an additive meeting the following requirement: (1) The additive has a higher oxidation potential than that of Ni so that grains of an additive-rich-oxide will form first during oxidation under a controlled atmosphere and grains of a Ni-rich-oxide, if any, will form subsequently and separately from the grains of the additive-rich oxide. (2) The additive has a tendency to segregate to the top surface. (3) The additive is not a catalyst poison for NiâP plating in the composition range.

International Classification:

B24B 700

US Classification:

451 54, 451 28

Abstract:

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 NiâP 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.

US Classification:

427438, 427129, 427131, 427132, 427405, 4274431

Abstract:

Abnormal nodule formation during electroless plating, e. g. , of amorphous NiP âseedâ layers utilized in the manufacture of magnetic recording media, is eliminated or substantially reduced by performing the electroless plating process in an apparatus employing polymeric or polymer-based materials which are substantially resistant to degradation upon prolonged contact with the electroless plating bath at an elevated temperature, i. e. , release of soluble, low molecular weight, carbon-containing species which are incorporated in the electroless plating deposit and act as nucleation centers for abnormal growth leading to nodule formation. Suitable degradation-resistant polymeric materials for use as fittings, piping, racks, tanks, etc. of the electroless plating apparatus include fluorine-containing hydrocarbons and fluorocarbons.

Abstract:

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.

US Classification:

385 11, 349194

Abstract:

A method and apparatus that includes a first waveguide segment that differentially changes the amplitude of the light relative to a first polarization orientation, a thickness of oriented liquid crystal or other birefringent material sufficient to delay one polarization component one-half wavelength relative to another, and a second waveguide segment that also differentially changes the amplitude of the light based on the polarization orientation. Also, an apparatus that includes a thin polarization converter that includes a thin first substrate that is substantially transparent to a wavelength of light, and a birefringent material deposited on one or more surfaces of the first substrate and oriented such that the polarization converter forms a half-wavelength birefringent plate for the light. Also, an apparatus having a first substrate surface, a second substrate surface, and a liquid crystal material between the first and second substrate surfaces to form a polarization converter.
