Abstract
A magnetic head includes a medium facing surface, a main pole, a trailing shield, a spin torque oscillator, and a first insulating layer. The first insulating layer is interposed between a portion of the main pole and a portion of the spin torque oscillator. The first insulating layer has a first end closest to the medium facing surface. The spin torque oscillator has a rear end farthest from the medium facing surface. The first end of the first insulating layer is located closer to the medium facing surface than the rear end of the spin torque oscillator is.
