Abstract
A device for processing optical data comprising a transparent substrate for a light to be applied, light source for projecting the diverging light onto one surface of the substrate substantially perpendicularly to the surface, lens provided on the substrate for causing the projected light to emerge obliquely or vertically upward from the other surface of the substrate and focusing the emergent light, photodetector provided on the substrate for receiving the light reflected from above, focusing drive mechanism for adjusting the position of the substrate upward or downward, and tracking drive mechanism for adjusting the position of the substrate laterally.
