Heat Assisted Magnetic Recording Head Comprising A Thermally Stable Material

A magnetic recording head, comprising:

• a main pole;
• a waveguide disposed adjacent to the main pole;
• a near field transducer (NFT) coupled between the main pole and the waveguide;
• a first insulating layer disposed between the NFT and the main pole;
• a second insulating layer disposed between the NFT and the waveguide;
• a thermal shunt disposed on the NFT, the thermal shunt being recessed from a media facing surface (MFS);
• and
• a thermally stable material disposed between the NFT and the MFS, the thermally stable material and the NFT comprising different materials, wherein the thermally stable material comprises:
• a first surface disposed at the MFS;
• a second surface disposed in contact with the NFT;
• a third surface disposed in contact with the second insulating layer;
• and
• a fourth surface disposed in contact with the first insulating layer.
