Store 256GB on an A4 sheet

By Chris Mellor, Techworld
How much information can you store on an A4 sheet? Well, according to some new technology designed by an Indian engineering student, an extraordinary 256GB.

New "rainbow technology", devised by Sainul Abideen who has just completed an MCA degree in Kerala, data can be encoded into coloured geometric shapes and stored in dense patterns on paper.
Files such as text, images, sounds and video clips are encoded in "rainbow format" as coloured circles, triangles, squares and so on, and printed as dense graphics on paper at a density of 2.7GB per square inch. The paper can then be read through a specially developed scanner and the contents decoded into their original digital format and viewed or played. The encoding and decoding processes have not been revealed.
Using this technology an A4 sheet of paper could store 256GB of data. In comparison, a DVD can store 4.7GB of data. The Rainbow technology is feasible because printed text, readable by the human eye is a very wasteful use of the potential capacity of paper to store data. By printing the data encoded in a denser way much higher capacities can be achieved.
Paper is, of course, bio-degradable, unlike CDs or DVDs. And sheets of paper also cost a fraction of the cost of a CD or DVD.
Abideen has demonstrated a 45-second video clip being encoded on paper, termed by him, a rainbow video disk - RVD - and then played back through a computer with an RVD scanner attached. In another demonstration he has shown 432 A4 pages of paper rainbow format-encoded and stored on a two-inch by two-inch square of paper.
He says that smaller scanners could fit inside laptop computers or mobile phones, and read SIM card-sized RVD's containing 5GB of data.
The recording media could be either paper or plastic sheets. Such media are making a comeback - witness yesterday's story about re-writable paper.

Un Saludo A4.

¡Hola a todos!

Vaya, creo que con esto el concepto de hoja de vida tomará un sentido más literal .

Ya me veo comprando El Conde de Monte Cristo de una sóla página y metiéndolo en un escáner A4-Decod marca Acme, para leerlo en una pantalla de arena nanofotoeléctrica.

Un abrazo en sobre.

Al González.

Que casualiad Al, acabo de leerlo por segunda vez, (lo había leido en francés hace años) y ahora lo he hecho en inglés.

Está claro que en ambas lenguas y alguna más podían entrar en un solo folio por una cara, debidamente codificado, claro que un fallo en el descodificado podría tener consecuencias funestas, vete a saber el nombre del personaje central: Edmond Morel?

Un Saludo con todas las letras.
