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.
