摘要
A microwave assisted magnetic head includes a main magnetic pole; a trailing shield; and a spin torque oscillator provided between the main magnetic pole and the trailing shield. The spin torque oscillator has a first end surface configuring a part of an air bearing surface, a second end surface facing the main magnetic pole, and a third end surface facing the first end surface, the first angle θ1 made by the first end surface and the second end surface is smaller than the second angle θ2 formed by the second end surface and the third end surface, and the second angle θ2 is 80 to 100 degrees.
