摘要： Provided is a thermally-assisted magnetic recording head comprising a near-field-light-generating (NFL-generating) optical system with an improved light use efficiency. The head comprises a magnetic pole, a waveguide propagating a light for exciting surface plasmon, and a NF-optical device configured to emit NF-light from its end surface located adjacent to the magnetic pole end surface. The waveguide cross-section, taken by a plane perpendicular to a waveguide edge along elongated direction, has substantially a trapezoidal shape in which a longer side of opposed parallel sides is an edge of the cross-section on the NF-optical device side. This configuration enables a coupled portion of the NF-optical device which is coupled with the light to be placed in the effective distribution range of the light seeping from the waveguide. Consequently, there can be realized a sufficiently strong coupling between the light seeping from the waveguide and the NF-optical device.

摘要： The invention provides a CPP-GMR device comprising a spacer layer. The spacer layer comprises a first nonmagnetic metal layer and a second nonmagnetic metal layer, each formed of a nonmagnetic metal material, and a semiconductor layer interposed between the first nonmagnetic metal layer and the second nonmagnetic metal layer, and further comprises a work function control layer formed between the first nonmagnetic metal layer and the semiconductor layer and/or between the second nonmagnetic metal layer and the semiconductor layer. The semiconductor layer is an n-type semiconductor, and the work function control layer is made of a material having a work function smaller than that of said first nonmagnetic metal layer, and said second nonmagnetic metal layer. It is thus possible to obtain by far more improved advantages: the semiconductor layer forming a part of the spacer layer can be so thicker than ever while keeping the area resistivity of the device low as desired, ever higher MR performance is achievable, and the variation of the area resistivity of the device can be substantially held back with much more improvements in film performance.
