    摘要: Thin lubricant films are prepared on optical and magnetic substrates by applying a lubricant having at least one UV polymerizable group onto the substrate and polymerizing the lubricant by UV irradiation at elevated temperatures. Embodiments include applying a lubricant having at least two acrylate groups onto a magnetic recording disc, heating the magnetic recording disc from about 50° C. to about 150° C. and exposing the lubricant to UV radiation substantially free of wavelengths of 200 nm or less.

    摘要: A system and method for corrosion problems in magnetic media resulting from moisture penetrating through the carbon layer into the magnetic layer by diffusion or other methods are overcome by processing the carbon overcoat to stop and/or inhibit the moisture penetration. The process involves removing moisture channels from protective overcoats of thin film magnetic media by irradiating the protective overcoat with ultraviolet (UV) radiation in an inert hydrophobic chemical environment. Afterwards, the thin film magnetic media can be removed into ambient atmosphere where it is coated with a lubricant.

    摘要: A system and method for improving the durability and reliability of recording media used in hard drives is disclosed. A protective overcoat made of diamond like carbon (DLC) is first deposited over a magnetic layer. A lubricant layer, typically containing Moresco lubricant or a perfluoropolyether (PFPE), is then deposited over the protective overcoat. Finally, the lubricant layer is exposed to ultraviolet (UV) light for a period of time.
