INTRODUCTION  Rainbow technology, a breakthrough in digital data storage

enables us to store up to a massive 450 GB on just a piece of paper.  Rainbow Storage is a group of techniques to store digital data in some colours, colour combinations and some symbols known as rainbow format, and therefore a rainbow picture will be generated.  With the help of Rainbow system we would be watching full-length high-definition videos from a piece of paper.

HOW IS IT POSSIBLE?

Data stored in rainbow format on an ordinary paper. 4

HOW IS IT POSSIBLE?(Contd…)  It uses geometric shapes such as squares and hexagons to

represent data patterns, instead of the usual binary method that uses ones and zeros to represent data.  Files such as text, images, sounds and video clips are encoded

in "rainbow format" as colored circles, triangles, squares and so on, and printed as dense graphics on paper at a density of 2.7GB per square inch.

5

HOW IS IT POSSIBLE?(Contd…)  Instead of using 0s and 1s, we use color dots where each color

dot can represent minimum 8 bits (1 byte). The rainbow picture will be highly compressed and can be represented in any color medium.  "Although environmental light differences and color shading is

a problem, it can overcome up to a certain limit by using efficient mapping functions".

PROCESS OF STORING DATA  Printing at 1,200 dots per inch (DPI) leads to a theoretical

maximum of 1,440,000 colored dots per square inch.  If a scanner can reliably distinguish between 256 unique colors,

the maximum possible storage is approximately 140 megabytes for a sheet of A4 paper.  If the scanner were able to accurately distinguish between

16,777,216 colors (24 bits, or 3 bytes per dot), the capacity would triple claims of several hundred gigabytes. 8

PROCESS OF STORING DATA(Contd…) At least one of three things must be true for the claim to be valid:  The paper must be printed and scanned at a much higher resolution than 1,200 DPI.  The printer and scanner must be able to accurately produce and distinguish between an extraordinary number of distinct color values  The compression scheme must be a revolutionary lossless compression algorithm.

COMPARISION WITH OTHER DEVICES  FLOPPY DISK : Only 1.44MB of space  USB memory stick(Pen-drive): Available from 1GB to

36GB.  CD/DVD’s : CD’s have storage space up to 700MB DVD’s have storage space 4.5 to 17GB  HARD DISK : Can hold anything from 3.75MB to 3 TB.

ADVANTAGES  The extremely low-cost technology will drastically reduce the

cost of storage and provide for high speed storage too.  Files in any format like movie files, songs, images, text can be stored using this technology.  The biodegradable nature of the storage devices would do away with the e-waste pollution.  The four main storage devices made using this technology are RVD, Disposable storage.

12

ADVANTAGES(Contd…)  Another theme put forward by rainbow technology is the Data

Banks. It is huge server with a high storage capacity.  As per a research project done in US in 2003 to store the

available static data, the server required will cost $500 crores(23000 crores). But by using data banks ,a similar server can be made with Rs.35 lacks.

13

DISADVANTAGES  The paper has the tendency to fade away hence the data

loss may occur.  With the extremely low cost of using this technology we

can always afford to have multiple copies.

14

FUTURE SCOPE  The developer is simultaneously moulding the technology into

'Rainbow Cards' which will be of SIM card size and store 5 GB of data equivalent to three films of DVD quality.  As 'Rainbow Cards' will become Popular, Rainbow Card

Readers will replace CD drives of mobile phone and computer notebooks  Large scale manufacture of the Rainbow card will bring down

its cost to just 50 paise 15

CONCLUSION  Once the Rainbow technology is in, soon we would be

watching full-length high-definition videos from a piece of paper!  With the popularity of the Rainbow Technology, computer or

fashion magazines in future need not carry CDs in a pack.  It should cost a lot less to produce than the typical

polycarbonate DVDs, CDs and now Blu- rays. Huge data banks can be constructed out of Rainbow-based storage medium. 16
