MAMR write head with thermal dissipation conductive guide

A magnetic recording head, comprising:

• a trailing shield;
• a main pole;
• side shields surrounding at least a portion of the main pole;
• a stack disposed between the main pole and the trailing shield;
• and
• a first structure disposed between the trailing shield and the side shields, wherein the first structure comprises:
• at least one layer of gallium nitride, gallium phosphide, hexagonal boron nitride, cubic boron nitride, boron arsenide, gamma magnesium aluminate, silicon, carbon, beryllium, tungsten, iridium, rhodium, molybdenum, diamond like carbon, or zinc oxide;
• and
• at least one layer of aluminum oxide, aluminum nitride, or silicon carbide.

A magnetic recording head, comprising:

• a trailing shield;
• a main pole comprising a first surface, a second surface, a third surface, and a fourth surface;
• a stack disposed between the first surface of the main pole and the trailing shield;
• a first structure surrounding the second surface, the third surface, and the fourth surface of the main pole at a media facing surface, wherein the first structure is fabricated from a material selected from the group consisting of:
• aluminum nitride, silicon carbide, beryllium oxide, gallium nitride, gallium phosphide, hexagonal boron nitride, cubic boron nitride, boron arsenide, gamma magnesium aluminate, zinc oxide, silicon, carbon, beryllium, tungsten, iridium, rhodium, molybdenum, diamond like carbon, and combination thereof;
• and
• a second structure disposed in contact with the trailing shield, the main pole, and the stack, wherein the second structure comprises:
• at least one layer of gallium nitride, gallium phosphide, hexagonal boron nitride, cubic boron nitride, boron arsenide, gamma magnesium aluminate, silicon, carbon, beryllium, tungsten, iridium, rhodium, molybdenum, diamond like carbon, or zinc oxide;
