The plating composition includes at least one sulfated fatty acid ester additive, or mixtures or salts thereof, of formula : wherein R1 is selected from the group consisting of OH, OCH2, OCH2CH3, C1-C7 alkyl, linear or branched; R2 selected from H and C1-C7 alkyl, linear or branched; m= 1 to about 5; n = 2 to about 30; o = 0 to about 10; M+ is a metal or pseudo metal ion or H+. The additive has a zeta potential which impedes deposit of non-metallic particles. The invention is further directed to a method for electroless plating utilizing the additive composition in a bath with at least a stabilizing agent, complexing agent and reducing agent and source of metal ions.

摘要： A plating bath for the electroless coating of magnetic recording media substrates includes cobalt, nickel, and zinc metal ions in a buffered solution including a reducing agent, a strong base, and chelating agents. Typically, the reducing agent will include phosphorous which will form a portion of the ferromagnetic layer being deposited on the substrate. By utilizing malic acid or a malate salt as a chelating agent, magnetic media having improved signal-to-noise ratios, switching field distributions, and corrosion resistance, have been obtained.

摘要： A process and apparatus for producing magnetic memory disks, and the like, of the type in which a thin layer of fine grain nickel/phosphorous paramagnetic material is first deposited on a large grain electrically conductive substrate, and a main magnetic layer is then electroplated over the nickel/phosphorous paramagnetic layer. In the practice of the method of the invention, the paramagnetic layer is electroplated onto the substrate through one or more openings in one or more rotating masks to provide directly a smooth fine grain layer of uniform density and thickness so as to obviate any necessity for time consuming and expensive polishing and burnishing operations of the paramagnetic film prior to the electroplating thereon of the main magnetic film; and the magnetic layer is also electroplated onto the paramagnetic layer through openings in one or more masks to provide a magnetic layer of controlled thickness for uniform magnetic response over the entire surface of the disk.

摘要： Described is a structural body including at least partially an aluminum member having on a surface an anodized film with micropores present, in which: the micropores have a coefficient of variation in pore size of 5 to 50%; and the micropores are each sealed with a metal. The structural body can generate localized plasmon resonance having a sufficiently large intensity and be produced at low cost through a simple production process, and having a large surface area.

摘要： This invention comprises the use, during the plating processing of thin-film magnetic recording media, of an oxidizing treatment immediately preceding the electroplating of the magnetic layer. This oxidizing treatment can be controlled to produce desired high levels of coercive force and low levels of media noise.

摘要： A bilayer oxide film (13) which comprises a preferably porous layer containing aluminum oxide (13A) and a non-porous layer comprising an oxide of a valve metal (13B), e.g. tantalum. The layers are integral. The film is produced by forming a coating (12) of aluminum or an anodizable aluminum alloy on a valve metal (or alloy) (11), anodizing the resulting structure in an electrolyte (preferably one capable of converting the aluminum (or alloy) to a porous oxide film) in the presence of an adhesion-reducing agent (e.g. fluoride ions) that makes the resulting anodized bilayer film (13) easily detachable from the remaining valve metal (11). The bilayer film (13) is then detached from the valve metal (11), e.g. by adhering a flexible plastic film (14) to the bilayer and using the film to peel off the bilayer from the valve metal (11). The resulting bilayer (13) can be used for a variety of purposes, e.g. as a vapour or oxygen barrier, or as a coating containing magnetic particles (16) used to make a magnetic recording medium.
