Abstract
An alignment method for bonding a first component to a second component is described. A plurality of sliders having alignment markers are substantially aligned to the alignment markers of a plurality of illumination units and then positioned into alignment by moving the slider with respect to the illumination unit by an offset. The offset is calculated by scanning a light source around the waveguide to determine the distance that the alignment markers of the slider are separated from the alignment markers on the illumination unit.
