HEAT ASSISTED MAGNETIC RECORDING (HAMR) HEAD WITH MAIN POLE HAVING A RECEPTION FOR PLASMA MATERIAL

A heat assisted magnetic recording (HAMR) head has a slider having a gas bearing surface (GBS). The slider supports a near field transducer (NFT) and a main pole having a step or recess in a surface facing the NFT near the GBS, the step or recess comprising a plasmon material. A thermal diverter is positioned between the NFT and the main pole to allow heat to be transferred away from a spot of light generated by the NFT. The NFT-facing surface of the main pole recessed from a step away from the GBS is in contact with the thermal diverter, and the thermal diverter is in contact with the plasmon material in a step in a rear region recessed from the GBS, so that the spacing between the NFT and a majority of the main pole is not increased. 一种热辅助磁记录(HAMR)头具有滑块，该滑块具有气体轴承表面(GBS)。该滑块支撑近场换能器(NFT)和主磁极，该主磁极在靠近GBS的面向NFT的表面中具有台阶或凹部，该台阶或凹部包含等离激元材料。热分流器定位于该NFT与该主极之间，以允许热量从由NFT产生的光点传递出去。从远离该GBS的台阶凹入的该主极的面向NFT的表面与该热分流器接触，并且该热分流器与从该GBS凹入的后部区域中的台阶中的等离激元材料接触，因此该NFT与该主极的大部分之间的间距没有增加。
