Patent ID: 7480214

Claim:
A data recording head for use in conjunction with a data recording medium, comprising: a body; a first waveguide supported by the body; and a second waveguide supported by the body and energy-coupled to the first waveguide, wherein the first waveguide has a first side having a first a first width and the second waveguide has a second side having a second width, the first width and the second width being measured in a direction of the space between the first waveguide and the second waveguide, wherein the first width is larger than the second width, wherein the first waveguide is configured to receive a propagated radiant energy directed from a source towards the first side, wherein the second waveguide is adjacent to the first waveguide such that the space between the first waveguide and the second waveguide is not aligned with the propagated radiant energy from the source, and wherein the propagated radiant energy is propagated from the first waveguide to the second waveguide across the space between the first waveguide and second waveguide.
