Thermally assisted magnetic head, head gimbal assembly, and hard disk drive

Image Number 13 for United States Patent #7957085.

A thermally assisted magnetic head has a slider substrate having a first surface located on the opposite side to a medium-facing surface, and side surfaces located between the medium-facing surface and the first surface; a magnetic head portion having a waveguide having a light exit face on the medium-facing surface side, and a magnetic recording element disposed in proximity to the light exit face, the magnetic head portion being fixed to one of the side surfaces of the slider substrate; a light source support substrate having a second surface facing the first surface; a light emitting element facing a light entrance face of the waveguide and fixed to the light source support substrate; and an adhesive interposed between the first surface and the second surface; at least one of the first surface and the second surface has a recess and the adhesive is disposed in the recess.
