Abstract:
1. A magnetic write head comprising: a magnetic write pole having a first and second sides and a trailing edge extending from the first side to the second side, the trailing edge having a tapered portion; a spin torque oscillator formed entirely on the tapered portion of the trailing edge of the write pole, and having first and second sides that are aligned with the first and second sides of the write pole; a non-magnetic side gap layer formed at the first and second sides of the write pole and first and second sides of the spin torque oscillator; a trailing, wrap-around magnetic shield that is separated from the first and second sides of the write pole and first and second sides of the spin torque oscillator by the first and second non-magnetic side gap layers; and a non-magnetic trailing gap layer separating the spin torque oscillator from a trailing portion of the trailing, wrap-around magnetic shield.
