Abstract
A magnetic head includes a medium facing surface, a main pole, a trailing shield, and a spin torque oscillator. A bottom surface of the trailing shield includes a first portion that includes an end located in the medium facing surface and is in contact with the spin torque oscillator at least in part. An element height that is a dimension of the spin torque oscillator in a direction perpendicular to the medium facing surface and a writer height that is a dimension of the first portion in the direction perpendicular to the medium facing surface are different from each other.
