INTRODUCTIONRainbow 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.

4

HOW IS IT POSSIBLE?

Data stored in rainbow format on an ordinary paper.

5

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.

6

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 DATAPrinting 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.

9

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 spaceUSB 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.

12

ADVANTAGESThe 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.

13

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.

14

DISADVANTAGESThe 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.

15

FUTURE SCOPEThe 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

16

CONCLUSIONOnce 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.
