Abstract
A magnetic head includes a main pole, a trailing shield, a spin torque oscillator, and a buffer layer. The buffer layer is interposed between the main pole and the spin torque oscillator. The spin torque oscillator has first and second side surfaces. The first and second side surfaces respectively form first and second angles with respect to a direction perpendicular to a top surface of a substrate. The first and second angles each fall within a range of 0° to 10°. The buffer layer has third and fourth side surfaces. The third side surface includes a first inclined portion forming a third angle greater than the first angle. The fourth side surface includes a second inclined portion forming a fourth angle greater than the second angle.
