摘要： A thermally-assisted magnetic recording head includes: a medium facing surface; a magnetic pole; a waveguide including a core and a cladding; a plasmon generator; and a protruding member. The protruding member is disposed between the medium facing surface and a front end face of the core facing toward the medium facing surface. The protruding member has a first end face located in the medium facing surface, and a second end face facing toward the front end face of the core and receiving light having propagated through the core and passed through the front end face. The protruding member is formed of a metal different from both a material forming the magnetic pole and a material forming the plasmon generator. The protruding member is heated and expanded by the light received at the second end face, so that the first end face gets protruded toward a magnetic recording medium.

摘要： Provided is a near-field light generator capable of avoiding a noise to the generated near-field light. The generator comprises a waveguide and a plasmon antenna comprising a propagation surface or edge, for propagating surface plasmon, extending to a near-field light generating end. A portion of one side surface of the waveguide is opposed to a portion of the propagation surface or edge, so as for the waveguide light to be coupled with the plasmon antenna. And an end surface of the waveguide is inclined in such a way as to become away from the plasmon antenna toward the near-field light generating end side. The light that propagates through the waveguide and is not transformed into surface plasmon is refracted or totally reflected in the inclined end surface, does not come close to the generated near-field light, thus does not become a noise for the generated near-field light.

摘要： A plasmon generator has an outer surface including a plasmon exciting part that faces an evanescent light generating surface of a waveguide. The outer surface further includes first and second inclined surfaces that increase in distance from each other with increasing distance from the plasmon exciting part, and a front end face. The front end face has first and second portions that are connected to each other into a V-shape. The first portion includes a first side lying at an end of the first inclined surface. The second portion includes a second side lying at an end of the second inclined surface. An angle formed between a lower part of the first side and a lower part of the second side is smaller than that formed between an upper part of the first side and an upper part of the second side.

摘要： A plasmon generator has an outer surface including a plasmon exciting part, and has a near-field light generating part located in a medium facing surface. The plasmon exciting part faces an evanescent light generating surface of a waveguide's core with a predetermined distance therebetween. The outer surface of the plasmon generator further includes first and second inclined surfaces that are each connected to the plasmon exciting part. The first and second inclined surfaces increase in distance from each other with increasing distance from the plasmon exciting part. The plasmon generator includes a shape changing portion where the angle of inclination of each of the first and second inclined surfaces with respect to the evanescent light generating surface increases continuously with decreasing distance to the medium facing surface.

摘要： Provided is a thermally-assisted magnetic recording head capable of setting the near-field light (NFL-) emission point to be sufficiently close to the write-field-generating portion. The head comprises a magnetic pole, a waveguide propagating light, and a NFL-generator coupled with the light in surface plasmon mode. The NFL-generator comprises a propagation edge extending to the NFL-generating end surface, at least a portion of the propagation edge being opposed to the waveguide with a distance, and the magnetic pole has a surface contact with a surface portion of the NFL-generator including no propagation edge. Therefore, the distance between the magnetic-pole end surface and the NFL-generating end surface becomes zero. The propagation edge is not contacted with the magnetic pole. Accordingly, the surface plasmon can propagate along on the propagation edge without being absorbed by the pole. Thus, the NFL-emission point is ensured to be at the end point of the propagation edge.
摘要翻译：提供了一种能够将近场光（NFL-）发射点设定为足够靠近写入场产生部分的热辅助磁记录头。磁头包括磁极，波导传播光和与表面等离子体激发光模式耦合的NFL发生器。 NFL发生器包括延伸到NFL生成端面的传播边缘，传播边缘的至少一部分与波导相距一定距离，并且磁极与NFL-发生端面的表面部分具有表面接触，发生器不包括传播边。因此，磁极端面与产生NFL的端面之间的距离为零。传播边缘不与磁极接触。因此，表面等离子体激元可以沿着传播边缘传播而不被极吸收。因此，确保NFL发射点处于传播边缘的终点。

摘要： The present invention provides a coil structure capable of improving a differential transmission characteristic by reducing capacitance as much as possible. A common mode choke coil is constructed so that a section of each of two coil patterns constructing a thin film coil has an inverted trapezoid shape which is bilaterally asymmetrical. Because of the structural characteristic that the section of each of the two coil patterns has an inverted trapezoid shape which is bilaterally asymmetrical, the facing area of the two coil patterns contributing to capacitance is minimized. Thus, the capacitance of the thin film coil can be reduced as much as possible.

摘要： A labyrinth ring having a section of L-shape is radially, inwardly and integrally projected from the inner periphery of a brush holder stay of a motor. This labyrinth ring provides a labyrinth construction in a space portion extending from brushes and a ball and roller bearing in cooperation with the brush holder stay, a commutator, a bearing holder and a distance ring. The thickness of this labyrinth ring is determined to be so thin as to increase the volume of a carbon accumulating space portion formed between the bearing holder and itself as large as possible.
