The Performance and Capacity of Rainbow Media

Today, most of data storage devices use digital storage type. In this thesis, a new digital storage media called rainbow disk was introduced. It doesn't use 1-bit digital signal, but 2 or 4 bits digital signal using colors, so it can increase $2{\sim}4$ times more capacity than existing digital media in case of having the same spot size. It has made possible by means of technological advancement of devices and software. The photo quality paper was used for writing data by color inkjet or laser printing, and high resolution scanner was used for reading data. To extract data from image, the converting program was used. This paper shows the concept of rainbow disk as well as its performance and capacity. Axiomatic design was used for evaluating and developing the whole system.
