PROBLEM TO BE SOLVED: To provide a magnetic head device set in a floating attitude by an air flow formed in its surface during movement of a recording medium, and capable of stabilizing the floating amount of a magnetic function unit by stabilizing the floating attitude of a slider even when a change occurs in the air density of a used environment. SOLUTION: On the side of the slider 10 of the magnetic head device facing a recording medium D, a front positive pressure surface 21 is formed before the application support point 7a of a pressing force, and an intermediate positive pressure surface 41 is formed after the application support point 7a in the intermediate part thereof. The intermediate positive pressure surface 41 is in a position protruded to the recording medium D side more than the front and rear positive pressure surfaces 21 and 31. When an air density is reduced, floating pressure applied on the front positive pressure surface 21 is reduced to lower a pick angleθp. However, the reduction of the magnetic function part 2 for bringing the intermediate positive pressure surface 41 close to the recording medium D to generate positive pressure is suppressed.
