Storing 5GB on a small piece of paper not only sounds like technology in reverse, but it sounds pretty hard to believe. But Sainul, a student at MES Engineering College in India, has developed a technique that he believes will not only do that, but can become the base technology for a practical and reduced cost banks of data.
"Sainul who has just turned 24, says, instead of using zeroes and ones for computing, he has used geometric shapes like circles, squares and triangles for computing which combine with various colours and preserve the data in images. An RVD therefore looks like a print-out of the modern art.
"In a demo at his college laboratory, this author could see text typed on 432 pages of foolscap paper being stored in a four square inch paper. The author was even shown a 45-second video clip of a Malayalam film stored on an ordinary paper piece. Sainul was guided by Prof. Hyderali, head of the MCA Department of the College in all these projects."
Huge data banks based using this paper technology could hold up to capacities of almost 125 Peta Bytes. In the nearer future, CDs and DVDs could (for some applications) be replaced by an RVD (Rainbow Versatile Disc), which would have capacities of between 90 and 450 GB.
It's the longest of long shots, but I suppose this is one rainbow that really could have a pot of gold at the end of it.
