Thermally assisted magnetic head, method of manufacturing the same, head gimbal assembly, and hard disk drive
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 thermally assisted magnetic head includes a base layer which a base groove part having a width gradually getting smaller along a depth direction and extending in an intersecting direction intersecting with the medium-opposing surface is formed. The near-field light generating layer has an in-groove generating layer formed inside of the base groove part. The in-groove generating layer is formed along an inner wall surface of the base groove part and has a thin-film like structure.
