In this research, a jitter-free optical storage media with high density is realized by using nano-spheres as digital recording bits. The media has an arranged structure composed of 300 nm diameter polystyrene spheres on the thin PMMA film. The optical shape signal reflected from nano-spheres is scanned with a confocal laser scanning microscope. A pickup reconstruction signal including a clocksignal is measured from the optical shape signal. This storage device is expected as a jitter-free media because no electrically-produced clocksignal is necessary for the pickup procedure.
