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 2.4μm 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 1.80μm, each disk can store data up to 8.1GB.
