Thermally-assisted magnetic recording head having expanded near-field light generating layer and method of manufacture
A thermally assisted magnetic head includes a main magnetic pole layer, a near-field light generating layer having a generating end part generating near-field light arranged within a medium-opposing surface, and an optical waveguide guiding light to the near-field light generating layer. The optical waveguide has a waveguide end face arranged within the medium-opposing surface and an upper end face on a side closer to the main magnetic pole layer. The thermally assisted magnetic head has an interposed layer which is in direct contact with an outer surface of the optical waveguide. The near-field light generating layer has a near-field light generating part having the generating end part and an expanded part connected with the near-field light generating part. The expanded part has a base part arranged above the upper end face of the optical waveguide and extended base part connected with the base part.
