Beschreibung
Zusammenfassung:	A magnetic head includes a main pole, a trailing shield, and a spin torque oscillator. A top surface of the main pole includes a first inclined portion, a second inclined portion, and a third inclined portion arranged in order of closeness to a medium facing surface. Each of the first to third inclined portions has a front end closest to the medium facing surface and a rear end farthest from the medium facing surface. Each of the first to third inclined portions is inclined relative to the medium facing surface and a direction orthogonal to the medium facing surface so that its rear end is located forward relative to its front end in a direction of travel of a recording medium.
