Abstract

Traditional optical storage technology focuses a laser beam on the surface of a disk using objective lenses. The storage capacity is limited. It entirely depends on the effective disk size. Using colored storage technology to increase the storage capacity is a novel approach. Color is used to store information. After the spectrometer reads the data, the original color is computed and the stored information is read. In this study, a color is used to write colors; optical transmission with a hybrid diffractive/refractive lens produces a transmission spectrum, and then the fiber-optic spectrometer reads and analyzes the color and then decodes the information. Based on a 2.4 μm reading spot size and the implementation of tricolor ink, ∼4.561  Gbytes can be stored. If the tricolor ink dripping and laser size can be reduced to 1.80 μm, each disk can store data up to 8.1 GB.
