    Abstract: An electrode for power storage devices includes: a resin layer having a first surface and a second surface that is located on an opposite side from the first surface; a first electrically-conductive layer that is disposed on the first surface side of the resin layer; and a first layer of particles that is disposed on an opposite side of the first electrically-conductive layer from the resin layer. In a cross section parallel to a thickness direction of the resin layer, the first electrically-conductive layer has a first shape including a plurality of protrusions that are convexed toward the resin layer and a recess that is disposed between two adjacent protrusions among the plurality of protrusions. A distance H along the thickness direction from one of top points of the two adjacent protrusions to a bottom point of the recess is smaller than a thickness of the resin layer.

    Abstract: A plasmon generator of a thermally-assisted magnetic recording head has a first configuration member having a near-field light generation end surface at an ABS, and a second configuration member being in contact with main magnetic pole, and terminating at a front end portion of a slope positioned at the position recessed from the ABS. An end part of a separator layer, which is interposed between the main magnetic pole and the first configuration member, on a side opposite to the ABS is at a position more recessed from the air bearing surface than the front end portion of the slope of the second configuration member.

    Abstract: The present invention relates to a plasmon generator, in which a surface plasmon is excited by application of light. The plasmon generator extends along one direction. The plasmon generator includes a first end surface that is positioned on one end in the one direction and at which near-field light is generated along with the excitation of the plasmon; and a second cross section that is substantially parallel to the first end surface and is away from the first end surface. The first end surface has a polygonal shape that does not have a substantially acute inner angle. The second cross section has an upper part that has a shape substantially the same as or similar to that of the first end surface and a flare shaped lower part that is connected to the upper part and has a width that increases as it is far from the upper part.

    Abstract: A current collector including: a resin layer having first and second surfaces; and a metal layer including aluminum. The metal layer includes a first metal layer located on a side of the first surface of the resin layer. A yield stress σY1 of the current collector is smaller than a tensile fracture stress σB2 of the resin layer. The current collector yield stress σY1 [MPa] is obtained by the following expressions (1) and (2) from a yield stress σY2 [MPa] of the resin layer, a resin layer thickness D2 [μm], a yield stress σY3 [MPa] of the metal layer, and a metal layer thickness D3 [μm]. σY1=A×σY3+(1−A)×σY2  (1) A=D3/(D2+D3)  (2) The metal layer yield stress σY3 [MPa] is obtained by the following expression (3) from a half-value width β [°] of an X-ray diffraction peak having the highest intensity in an X-ray diffraction pattern of the metal layer. σY3=(−259+1285×√β)  (3)

    Abstract: A thermal assisted magnetic recording head of the present invention has an air bearing surface (ABS) opposite to a magnetic recording medium, a core that can propagate laser light as propagating light, a plasmon generator that includes a generator front end surface facing the ABS, and a main pole that faces the ABS and emits magnetic flux to the magnetic recording medium. The plasmon generator is opposite to a part of the core and extends to the generator front surface, is coupled with a portion of the propagating light that propagates through the core in the surface plasmon mode to generate a surface plasmon, propagates the surface plasmon to the generator front end surface, and generates near-field light (NF light) at the generator front end surface to irradiate the NF light to the magnetic recording medium. The ABS has a protrusion that is closer to the leading side than the generator front end surface in the down track direction, and that protrudes more toward the magnetic recording medium than the generator front end surface upon operation of the thermal assisted magnetic recording head.
