Abstract

In this study, a submicron-particles-arrayed optical storage disk was fabricated by the spin coating method. Moreover, we have formed a multi-valued pit by irradiating linearly polarized laser beams at multiple angles (0° and 90°). The optical setup has the semiconductor laser (λ = 637 nm) for reconstructing and the SHG-YVO4 laser (λ = 532 nm) for recording. The optical setup measured the submicron-particles-arrayed optical storage as a confocal image by 2D scanning with a motorized stage.
