Abstract: A magnetic head device is provided. A slider of a magnetic head device has a side that faces a recording medium and on which a first positive pressure is exerted on the leading side and a second positive pressure is exerted on the trailing side. In the area between the first positive pressure area and the second positive pressure area, a small second negative pressure is created at the front. A first negative pressure larger than the second negative pressure is created at the rear. A third positive pressure is exerted on both sides of the first negative pressure area. When air density decreases, the small second negative pressure in a middle area and the large first negative pressure at the rear of the second negative pressure area stabilize the pitch angle of the slider and prevent an excessive decrease in the flying distance of a trailing end portion.

Abstract: A magnetic head slider and a fabrication method for the magnetic head slider are provided in which a change in crown profile shapes resulting from a temperature difference is suppressed. The magnetic head slider includes a read/write element integrated on a slider body. A medium-facing surface of the slider body disposed to face a recording medium is subjected to crown processing. Both longitudinal ends of a slider-bottom surface disposed opposite the medium-facing surface are bonded to a suspension by means of resin adhesive. In this case, the slider-bottom surface is entirely coated with a film having a thermal expansion coefficient smaller than that of the slider body so as to suppress thermal deformation.

Abstract: A magnetic head device floats above a surface of a rotating recording medium due to airflow. A front positive-pressure surface is formed in the leading side of an opposed surface of a slider, and a rear positive-pressure surface is formed in the trailing side. A front edge portion of the rear positive-pressure surface has a shape recessed toward the trailing side, and a concave portion is formed from the front edge portion toward the magnetic functional unit. Airflow flowing between the slider and the recording medium is concentrated in the rear of the concave portion. When the magnetic functional unit emits heat and thus a portion projects toward the recording medium, a decrease in the floating distance of the magnetic functional unit can be counteracted by the local positive pressure of the airflow concentrated locally.

Abstract: A magnetic head apparatus including a magnetic head slider having an overall front half region area (S) and a step surface area (S1) and a positive-pressure generating surface area (S2) both in the front half region, such that the area ratio S1/S is about 0.180 to about 0.232 and the area ratio S1/S2 is about 0.30 to about 0.47. With this arrangement a difference in pitch angles of the magnetic head slider at the moment when it is just levitated and during levitation is large, and a variation of the pitch angle due to a pressure change is small, thereby preventing damage to a magnetic element within the magnetic head slider while achieving a stable levitation attitude of the magnetic head slider.

Abstract: The present invention provides a magnetic head slider including rails formed on the medium-facing surface on the magnetic disk side for generating buoyant force so that the slider flies and moves above a magnetic disk to write or read magnetic information. In the magnetic head slider, a first carbon film having corrosion resistance is provided on the surfaces of the rails provided on the medium-facing surface of the slider body through an adhesive layer, protrusions formed by alternately laminating an intermediate film and a second carbon film are provided on the first carbon film, and at least the outermost second carbon film of the second carbon films, which constitute each of the protrusions, has abrasion resistance.

Abstract: A trailing ABS face, which is a surface generating positive pressure, is formed to rise from a surface facing a recording medium, which is a surface generating negative pressure, toward the recording medium and furthermore, a surface facing the element, in which a gap portion of a magnetic element is located, is formed to rise from the trailing ABS face. Thereby, the floating lift of a magnetic head can be reduced while the floating position can be stabilized and furthermore, collision of the magnetic head with a disk surface can be properly avoided.

Abstract: The use of a Nd-YAG laser or excimer laser enables easy formation of protrusions on a protecting layer and a portion of an opposite surface near the trailing side end thereof and a thin film element. It is thus possible to avoid direct contact between the thin film element and the disk surface, and thus prevent damage to the thin film element and wearing thereof even if a slider and the disk surface repeatedly slide on each other.
