Technology geared up more : DVD holds 2,000 movies now May 23, 2009

A recent research by scientist and their continuous efforts to present a upgraded DVD technology that can hold now more than 2,000 movies revolutionizing the way we store films, music and data.

The DVD is featured with nano-technology to store vast amount of information. They are eying this up gradation in next 5 years and planning to launch it in the market.

The breakthrough comes from Swinburne University of Technology, Melbourne, Australia, where scientists created a prototype using ‘nano rods’ – tiny particles of gold too small to see – and polarised light, in which the light waves only flow in one direction, reported Daily Mail.

A conventional DVD records music, pictures and computer files as digital code – a series of ones and zeroes. The code is written as a series of pits under the clear surface of the disc and is read by a DVD player’s laser.

The new disc stores information using two extra ‘dimensions’ – the color of light and the direction, or polarization, of light waves.

“These extra dimensions are the key to creating ultra-high capacity discs.

More information can be fetched on the link posted below. Hope u guys are looking forward at this up gradation too.
