Abstract:
The disclosure is for a film coating which yields increased life for optical media molds and the method and apparatus for making such a film. The film is a carbon nitride layer of 0.5 to 5.0 microns thickness with 2% to 45% nitrogen coated on an underlayer. One method of making the carbon nitride film is by the use of a pulsed carbon arc to generate a carbon plasma while injecting nitrogen into the vacuum chamber in which the arc is created. Another method is to generate a radio frequency plasma in a vacuum chamber into which acetylene and nitrogen gas are injected. The carbon nitride is formed by the combination of nitrogen with the carbon from the acetylene.
Abstract:
A nitride material comprises C.sub.2 N. A method of forming a covalent carbon material includes forming an atomic nitrogen source, forming an elemental reagent source and combining the atomic nitrogen, elemental reagent to form the covalent carbon material and annealing the covalent carbon material. The elemental reagent is reactive with the atomic nitrogen of the atomic nitrogen source to form the covalent carbon material. Annealing the covalent carbon material produces the C.sub.2 N. In one embodiment, essentially all carbon nitride chemical bonds are single or double bonds.
Abstract:
A hard protective material and method for forming the medium having the formula C.sub.x N.sub.y. The medium may be formed as a protective film on a magnetic recording disk in a sputtering apparatus such as a magnetron apparatus. The amount of nitrogen in the film may be affected by controlling the collisions of the sputtered material between the target and deposition substrate by controlling the bombardment of the substrate by electrons. The films exhibit properties indicative of a textured morphology on a nanoscale which enhances the retention of lubricant overcoats.

According to one embodiment, there is provided a method for manufacturing a magnetic recording medium, the method including: depositing a magnetic recording layer on a substrate; forming a mask on a region of the magnetic recording layer corresponding to a recording area; irradiating another region of the magnetic recording layer where the mask is not formed with an ion beam using a C-containing gas as a source gas to deactivate the another region and to thereby form a non-recording area; and forming a protective film over an entire surface of the substrate.
Abstract:
The invention relates in general level to a method for coating various products including large surface areas with carbon nitride material. The invention also relates to carbon nitride coated products manufactured by the method. The coating is carried out by employing ultra short pulsed laser deposition wherein pulsed laser beam is scanned with a rotating optical scanner including at least one mirror for reflecting the laser beam. The invention has several both industrially and qualitatively advantageous effects such as high coating production rate, excellent coating properties and overall low manufacturing costs.
Abstract:
A method for sputtering a thin film protective layer with improved durability is disclosed. The method reduces kinetic energy of the ions of the overcoat material during the initial period of deposition to form a buffering interface which reduces the interpenetration of the atoms of the protective layer into the underlying film. In the method of the invention the sputtering of the overcoat preferably begins with zero (or very low) voltage applied to the underlying film resulting in minimal ion implantation in the underlying film. The “high energy” phase of the process begins with increases in the magnitude of the negative bias voltage applied to the underlying film. The higher energy imparted to ions in the plasma result in a denser and harder film being formed over the initial buffer layer. The protective layer preferably comprises carbon and nitrogen.
Abstract:
A method for producing a magnetic recording medium in which the noise of the magnetic recording medium is reduced and the thermal stability of the recorded magnetization is improved, while enabling easy writing to be carried out by a recording head, is disclosed. The magnetic recording medium of the present invention includes an underlayer having an hcp crystal structure and a magnetic layer produced by a multilayer lamination of Co/Pt or the like. The deposition rate of the underlayer is equal to or lower than 0.7 nm/second. The magnetic layer contains added silicon oxide at 1 to 10 mol %. The present method includes a step for subjecting the surface of the underlayer to Ar gas mixed with oxygen of a mass/flow rate ratio of 1% to 10% under a gas pressure of 0.1 to 10 Pa for 1 to 10 second(s). The magnetic recording medium may include an orientation control layer and a soft magnetic backing layer. Ku, Ku1, and Ku2 are controlled to provide both of thermal stability and easy writing.
