Thermally assisted magnetic recording head having V-shaped plasmon generator |
摘要 |
A thermally assisted magnetic head includes a magnetic pole that generates a writing magnetic field from an air bearing surface (ABS); a waveguide through which light propagates; and a plasmon generator generating near-field light from a near-field light generating end surface by coupling the light thereto in a surface plasmon mode. The magnetic pole includes a convex part protruding in a substantially V-shape along a light propagation direction of the waveguide. The plasmon generator includes a substantially V-shaped part contacting the convex part, and as seen from a side of the ABS, a thickness of the plasmon generator in a direction perpendicular to convex part contacting sides gradually increases from an end in a direction away from the waveguide, the convex part contacting sides being linear sides that form the substantially V-shaped part of the plasmon generator and contacting the convex part.
