Abstract
An apparatus includes a solid immersion mirror with opposing, reflective, inner sidewalls having inner surfaces facing a focal region and outer surfaces opposite the inner surfaces. The solid immersion mirror also include opposing outer sidewalls spaced apart from and facing the outer surfaces of the inner sidewalls, and a fill material between the inner sidewalls and outer sidewalls. The apparatus also includes a near-field transducer located in the focal region proximate a media-facing surface.

An apparatus comprising:
- a solid immersion mirror comprising:
- opposing, reflective, inner sidewalls having inner surfaces facing a focal region and outer surfaces opposite the inner surfaces;
- opposing outer sidewalls spaced apart from and facing the outer surfaces of the inner sidewalls;
- and
- a thermally conductive fill material between the inner sidewalls and outer sidewalls, the thermally conductive fill material extending to a media-facing surface;
- and
- a near-field transducer located in the focal region proximate the media-facing surface, wherein the thermally conductive fill material protrudes from the media-facing surface during heating to form a landing pad that protects the near-field transducer from contact with a recording medium.

A method comprising:
- forming opposing, reflective, parabolic inner sidewalls having inner surfaces facing a focal region and outer surfaces opposite the inner surfaces;
- forming opposing outer sidewalls spaced apart from and facing the outer surfaces of the inner sidewalls;
- depositing a thermally conductive fill material between the inner sidewalls and outer sidewalls, the thermally conductive fill material extending to a media-facing surface;
- and
- forming a near-field transducer located in the focal region proximate a media-facing surface, wherein the thermally conductive fill material protrudes from the media-facing surface during heating to form a landing pad that protects the near-field transducer from contact with a recording medium.
