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.
