A magnetic head slider for writing or reading magnetic information while flying above a magnetic disk, includes a slider body provided with a magnetic head core, and a rail and/or a pad for generating lift, provided on the surface facing a recording medium of the slider body. A crown is formed at least at a position on the rail selected from the group consisting of the surface facing the recording medium of the slider body, the rail, and the pad. The rail includes side-rails formed on both sides of the surface facing the recording medium of the slider body and extending from the air inflow side to the air outflow side of the slider body. A groove is provided between the side-rails. At least one protrusion is provided on each side-rail on the air inflow side and/or on each side of the groove on the air inflow side. The protrusion protrudes more toward the magnetic disk than the side-rails.
