    • A plasmon generator positioned away from the substrate and extending to the air bearing surface (ABS) as facing a part of the waveguide. The plasmon generator has a propagation edge extending in a longitudinal direction. The propagation edge has an overlapping part overlapping the waveguide in the longitudinal direction, and a near field light generator positioned on the ABS and located in the vicinity of the edge part of the recording magnetic pole. The overlapping part of the propagation edge is coupled with the laser light propagating through the waveguide in a surface plasmon mode so that a surface plasmon is generated. The propagation edge propagates the surface plasmon generated in the overlapping part to the near field light generator. The magnetic recording element further has a grounding element electrically connecting the plasmon generator and the substrate.
    • 等离子体发生器远离基板定位并且面向波导的一部分延伸到空气轴承表面(ABS)。 等离子体发生器具有沿纵向方向延伸的传播边缘。 传播边缘具有在纵向上与波导重叠的重叠部分,以及位于ABS上且位于记录磁极的边缘部分附近的近场光发生器。 传播边缘的重叠部分与以表面等离子体模式传播通过波导的激光耦合,从而产生表面等离子体激元。 传播边缘将在重叠部分中产生的表面等离子体激元传播到近场光发生器。 磁记录元件还具有电连接等离子体发生器和基板的接地元件。

    • A plasmon generator has a near-field light generating part located in a medium facing surface. The plasmon generator has an outer surface including a plasmon exciting surface and a plasmon propagating surface that face toward opposite directions. The plasmon exciting surface is substantially in contact with an evanescent light generating surface of a waveguide's core. The plasmon propagating surface is in contact with a dielectric layer that has a refractive index lower than that of the core. The plasmon exciting surface includes a first width changing portion. The plasmon propagating surface includes a second width changing portion. Each of the first and second width changing portions has a width that decreases with decreasing distance to the medium facing surface, the width being in a direction parallel to the medium facing surface and the evanescent light generating surface.
    • 等离子体发生器具有位于介质面对表面中的近场光产生部分。 等离子体发生器具有外表面,其包括面向相反方向的等离子体激元表面和等离子体激元传播表面。 等离子体激元表面基本上与波导芯的瞬逝光产生表面接触。 等离子体激元传播表面与折射率低于芯的折射率的电介质层接触。 等离子体激元表面包括第一宽度改变部分。 等离子体激元传播表面包括第二宽度改变部分。 第一和第二宽度改变部分中的每一个具有随着到介质面对表面的距离的减小而减小的宽度,宽度在平行于介质面向表面和渐逝光产生表面的方向上。
