Abstract
A magnetic recording head is provided with a main magnetic pole that generates a recording magnetic field to be applied to a magnetic recording medium from an end surface which makes a portion of an air bearing surface, a trailing shield that is placed by interposing a write gap at a trailing side of the main magnetic pole, a spin torque oscillator that is placed within the write gap to be between the main magnetic pole and the trailing shield, and two side shields that are placed at both sides of the main magnetic pole in the cross track direction, and when viewed from the air bearing surface side, at least a portion of the trailing-side end surfaces of the side shields are offset toward a leading-side of the main magnetic pole from the leading-side end surface of the spin torque oscillator.
