Magnetic head with assisted magnetic recording and method of making thereof
A magnetic head includes a main pole configured to serve as a first electrode, an upper pole containing a trailing magnetic shield configured to a serve as a second electrode, and a record element located in a trailing gap between the main pole and the trailing magnetic shield. The record element includes an electrically conductive, non-magnetic material portion which is not part of a spin torque oscillator stack. The main pole and the trailing magnetic shield are electrically shorted by the record element across the trailing gap between the main pole and the trailing magnetic shield such that an electrically conductive path is present between the main pole and the trailing magnetic shield through the record element.
