A magnetic head device is disclosed. The magnetic head device having a levitation attitude formed by an air stream on a surface thereof when a recording medium moves. A levitation height of a magnetic function unit can be stabilized even when air density of an operating environment is changed. In a middle region of a slider of a magnetic head device, a deep concave bottom portion is provided and a levitation pressure is not substantially generated. The levitation is exerted to a front positive pressure surface located in front of the middle region and a rear positive pressure surface located in the rear of the middle region.
