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.
