Abstract
A microwave assisted magnetic head is equipped with a main magnetic pole that generates a recording magnetic field to be applied to a magnetic recording medium from an end surface forming a portion of an air bearing surface opposed to the magnetic recording medium, a trailing shield that is disposed interposing a write gap at a trailing side of the main magnetic pole, and that forms a magnetic path with the main magnetic pole, two side shields that are disposed at both sides of the main magnetic pole in the cross track direction, respectively, and a spin torque oscillator that is disposed within the write gap. The write gap is configured to substantially linearly extend along the cross track direction when viewed from an air bearing surface side, and is positioned between trailing-side end surfaces of the main magnetic pole and the two side shields, and a leading-side end surface of the trailing shield.
