    摘要： There are provided a composition that exhibits sufficient flowability and also displays high substrate adhesion, and a magnetic recording medium, a head slider and a magnetic recording device that use this composition as a lubricant and are thus not prone to faults. The composition comprises a fluorine-containing polyether represented by formula (1), (in formula (1), p and q represent, independently of the symbols in other formulae, any chosen integers). The composition can be produced by reacting a polymer represented by formula (2) with glycidol, HOCH2CF2O(CF2CF2O)p(CF2O)qCF2CH2OH   (2) (in formula (2), p and q represent, independently of the symbols in other formulae, any chosen integers).

    摘要： A head slider to which little amount of contaminants is adhered, that can form a uniform and flat head lubricant layer surface and that has excellent ultra-low floating properties, as well as a magnetic recording device equipped with the head slider are provided. The head slider is equipped with a head slider lubricant layer having an average film thickness of not more than 2.5 nm, and composed of a water-repellent resin, the lubricant layer being formed on the head slider surface and head slider protection layer surface facing the magnetic recording medium, and the surface tension of the head slider lubricant layer determined by the Fowkes equation is not more than those of the head slider surface and head slider protection layer surface.
