摘要:
An apparatus includes a component having a first surface, a first waveguide for directing electromagnetic radiation to a focal point adjacent to the first surface, a storage medium positioned adjacent to the first surface, a detector for detecting electromagnetic radiation reflected from the storage medium, and a structure positioned adjacent to the focal point for collecting the reflected electromagnetic radiation and for transmitting the reflected electromagnetic radiation toward the detector, wherein the structure comprises a second waveguide including a first cladding layer positioned adjacent to a first side of the first waveguide and having a first end positioned adjacent to the first surface and a second cladding layer positioned adjacent to a second side of the first waveguide and having a first end positioned adjacent to the air bearing surface.
