Rainbow technology, a breakthrough in digital data storage, allows us to store up to 450 GB on a single piece of paper. Rainbow Storage is a group of techniques to store digital data in some colours, combinations of colours and some symbols known as rainbow format, so that a rainbow image will be generated.
Rainbow Storage is a paper-based data storage technique that is first demonstrated by the Indian student Sainul Abideen in November 2006. Abideen received his MCA from the MES Engineering College in Kuttipuram in the Malappuram district of Kerala .
Initial reports from technology journals were disputed by multiple technical sources, although Abideen says that those reports were based on a misunderstanding of technology. The paper was intended to demonstrate the ability to store relatively large amounts of data (and not necessarily in the range of gigabytes) using textures and diagrams.
Rainbow's data storage technology aims to use geometric shapes such as multi-colored triangles, circles, and squares to store a large amount of data on ordinary paper or plastic surfaces. This would provide several advantages over current forms of optical or magnetic data storage, such as less environmental pollution due to paper biodegradability, low cost and high capacity. Data can be stored in Rainbow Versatile Disk (RVD) or plastic / paper cards of any shape factor (such as SIM cards).
