Abstract
A magnetic recording head comprises: a main magnetic pole for generating a recording magnetic field applied to a magnetic recording medium from an end surface that is one part of an air bearing surface facing the magnetic recording medium; a trailing shield that is placed by interposing a write gap at a trailing side of the main magnetic pole; and a spin torque oscillator provided in the write gap; wherein, when viewed from the air bearing surface side, the length in the down-track direction between the trailing shield and the cross-track direction end portion of a first end face positioned at the main magnetic pole side of the spin torque oscillator is longer than the length in the down-track direction between the trailing shield and the main magnetic pole at a center position in the cross-track direction of the spin torque oscillator.
