    摘要： Formation of a Sm-Co alloy film is carried out by means of wet plating system which is easily practicable and well suited for treatment intricate and/or large configurations. The system uses a plating bath which contains chlorides of samarium and cobalt dissolved with non-aqueous solvent such as formamide. Substantial absence of any aqueous components in the plating bath assures production of a plated film of high purity and quality. Content of samarium in the product can feeely be adjusted by choice of the current density of direct current to be employed in the electrolytic plating.

    摘要： A process for producing magnetic plated media suitable for use in high-performance disk drives is disclosed. A layer of nickel is first provided on a standard aluminum alloy substrate, by electroless deposition, to improve adhesion of subsequent layers. A layer of nickel phosphorous and a magnetic layer of nickel cobalt are then, in turn, electroplated. The plated media disk is then oxidized below a nickel-magnetizing temperature to provide a protective outer surface.A variation of this process is also disclosed. This time a magnetically-shielding copper layer is electroplated over the first nickel layer. The nickel phosphorous and nickel cobalt layers are then electroplated on as before. The plated media can now be oxidized at a temperature higher than the nickel-magnetizing temperature to speed up the process.

    摘要： A small diameter magnetic film plated wire for memory devices is constructed utilizing an inner core selected from the group consisting of tungsten and molybdenum. In a preferred embodiment of the magnetic film plated wire, a tungsten core is successively overlaid with a gold strike layer, a rapidly deposited relatively thick copper conductive layer, a slowly deposited smooth copper layer, a gold layer and a circumferentially oriented magnetic nickel-iron film.

    摘要： A PROCESS FOR TREATING THE SUBSTRATE OF A THIN MAGNETIC FILM TO OBTAIN A SURFACE STATE WHICH REDUCES THE SENSITIVITY OF THE FILM TO STRAY MAGNETIC FILEDS AND WHICH IMPROVES THE NON-DESTRUCTIVE READOUT PROPERTIES OF THE FILM, WHEREIN, PRIOR TO BEING COATED WITH THE MAGNETIC FILM, THE SUBSTRATE IS IMMERSED IN AN ACID ELECTROLYTIC BATH AND EMPLOYED AS AN ELECTRODE IN SUCH BATH, AND WHEREIN THE ATACK ON THE SUBSTRATE IN THE BATH IS CONTROLLED BY A CURRENT OF CONSTANT DENSITY ALONG THE LENGTH OF THE SUBSTRATE.
