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.
