In a recording transducer, radiant energy is incident to be coupled to a
recording head via a path defined in the support (e.g., slider) for the
head. The radiant energy may be directed via a fiber or lens (e.g., MEMS
lens) through a channel defined in the slider. The slider may be keyed to
accept the fiber or lens. The process for fabricating the channel in the
slider the channel may include wafer level processing to form holes in
the slider, to accept the fiber or lens. Wafer level MEM optical
processing may be deployed to form integrated MEMS lens structures for an
array of sliders.
