摘要:
Disclosed herein are methods that include inserting a magnetic media into an enclosure and using a non-thermal physical vapor deposition process to deposit a lubricant onto the magnetic media within the enclosure. Also disclosed are methods that include loading a magnetic media that includes a tribological coating into an enclosure and using an electrospray ionization process to deposit a lubricant onto the magnetic media within a vacuum created by the enclosure.
摘要:
An equipment and method for inline infrared (IR) ultraviolet (UV) irradiation of recording media is disclosed. The components of the equipment include a saddle for holding a recording medium such as a disc, a conveyor that travels the saddle through a tunnel in which one or more IR and UV lamps are positioned to direct IR and UV light on the recording media traveling through the tunnel. The efficacy of the bonding of the lubricant to the recording medium by UV light is substantially enhanced by exposing the recording medium to IR light prior to exposure to UV light.
摘要:
A lubricant composition comprising a first fluoropolyether and a second fluoropolyether having nitrogen containing end-group exhibits improved resistance to acid and thermal decomposition. Embodiments include a lubricant composition containing a perfluorinate polyalkylether admixed with a perfluorinated polyalkylether having amide terminal groups and applying the composition to the surface of a magnetic recording medium to form a homogeneous lubricant topcoat thereon.
摘要:
A fluoropolyether having a nonfunctional silane end group is applied to a magnetic recording medium to form a lubricant topcoat thereon. In an embodiment of the present invention, no less than about 70% of the lubricant applied to the magnetic recording medium forms a bonded topcoat thereto.
摘要:
A perpendicular magnetic recording medium having a substrate, a Cr-doped Fe-alloy-containing underlayer containing about 8 to 18 at % Cr and a perpendicular recording magnetic layer, and a process for improving corrosion resistance of the recording medium and for manufacturing the recording medium are disclosed.
摘要:
A magnetic data storage medium may include a substrate, a magnetic recording layer, a protective carbon overcoat, and a monolayer covalently bound to carbon atoms adjacent a surface of the protective carbon overcoat. According to this aspect of the disclosure, the monolayer comprises at least one of hydrogen, fluorine, nitrogen, oxygen, and a fluoro-organic molecule. In some embodiments, a surface of a read and recording head may also include a monolayer covalently bound to carbon atoms of a protective carbon overcoat.

摘要:
A method, in one embodiment, can include pumping a gas into a reservoir that includes a lubricant. In addition, the method can include changing the gas into a supercritical fluid that extracts lubricant molecules from the lubricant resulting in a mixture of the supercritical fluid and the lubricant molecules. Furthermore, the method can include utilizing the mixture to deposit a lubricant molecule onto a magnetic media.
