Abstract: 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.

Abstract: A lubricant layer for a magnetic recording medium may include a perfluoropolyether having monomer units and end groups selected to provide high thermal stability and good reliability.

Abstract: An overcoating for electronic devices, such as magnetic recording devices, includes an intermediate layer formed adjacent to or on the device and a protective layer formed adjacent to or on the intermediate layer. The intermediate layer and protective layer may have a combined thickness in the range of about 6 angstroms to about 35 angstroms. The intermediate layer may be formed of a material such as silicon, aluminum or boron containing borides, carbides, nitrides, oxides or oxynitrides. The protective layer may be formed of a metal oxide material.

Abstract: A patterned magnetic storage medium has a plurality of data sectors separated by respective servo sectors with each servo sector having a pattern of pits representing servo data. Grooves in each data sector separate adjacent tracks. Non-uniform structures patterns the grooves to a model of minimum or zero fly height perturbations of a slider adjacent the medium. The non-uniform structures preferably include lands pseudo-randomly spaced along each groove to form segmented grooves of pseudo-random length, with the lands being pseudo-randomly positioned across the data sector. In other embodiments, the servo sectors have lengths along each track to define a null frequency that matches a pitch frequency of modulation of a slider due to the pits of the servo sectors.
