Front illumination is the fastest type of optical disk. Front illumination also allowed us to design a very small and light head with a beam size of 1 mm. It also allowed us to use an opaque aluminum substrate, which can rotate at high speeds. If optical disks are mounted in an enclosure like those for hard disks, they are protected from contamination and front illumination would be practical.
