Store 450GB of Data on an A4 sheet Paper
An Indian engineering student has developed a data storage technology called “Rainbow Technology”. The best feature of this technology is the data is stored in ordinary paper using geometric shapes instead of digital format. 
Using this technique around 450GB (a modern Blu-ray disc can hold max of 50GB) of data can be stored on a single A4 sheet paper. To retrieve your data is all you need is a scanner and some specialized software which can analyze and decode your data. A paper with fully loaded data will actually look like a random modern art painting. 
My View:
We actually need this kind of innovation at this point of time when we are in need of large data storage media.
Things I would like to know more about this technology?
- The data transfer rates.
- The reliability of data on the paper or plastic paper against day to day use.

This isn’t the first time this has been done:

Also, PC Magazine (or was it BYTE Magazine?) in the late 1980s or very early 90s used to include small utilities/tools in their advanced/technical columns. Some of the longer programs were provided in a scannable format which could be read by a small manually entered tiny scanner program (which was provided as machine code, entered in DOS debug).
with the research advance in artificial neural network technology, one can scan the contents in paper to desired accuracy, by training with few set of input data. i certainly hope that this innovation will not be stopped here and will continue till they find a substitute to digital storage media.
of course, there should be a (healthy) comptetition between traditional paper and digital media, only then we can find innovative technology with creative ideas from the brilliant minds of younger generation people B-).
I read somewhere on Digg that this story was a scam..
Here’s the link: http://digg.com/tech_news/Scam_of_Indian_student_developing_technology_to_store_450_GB_on_paper
It was a scam indeed and it isn’t the first one.
Ya, I also read that it is a scam and not true
U mean all such stories were scam .
No Madhur,we mean this story was a scam.But of course there are many others out there trying to full the naive.
