Developed Hard Drive from Glass

LONDON - British scientists will make the hard drive to store data on computer devices using hard kaca.Perangkat is similar to that seen in the crystal memory Superman movie.Scientists from Southampton University, uses a laser beam in order to rearrange the atoms in the pieces of glass and turn it into a new type of memory on the computer.

They claim that the memory glass is much more stable and durable than other types of hard drive memory, which has limited durability in recent decades, and vulnerable to damage caused by high temperatures and humidity.

Memory is made of glass, can survive temperatures up to 1800 Fahreheit, not affected by water and stored information that can last up to thousands of years. "Information can be written, deleted and edited in the molecular structure of glass by using laser light," said the scientists, as quoted by The Telegraph, Monday (15/08/2011).

The process by changing the path of light into the glass, thus creating a vortex of light polarization (one of the properties of light that moves oscillasi and towards a certain direction) which can then be read through a lot of ways, as well as data on optical fiber.

Memory glass has been compared to "crystalline memory" used in the Superman movie, which contains a recorded video and data stored by her parents when played back on a crystal.

Martynas Beresna, leader of the study states that this device has a capacity equivalent to Blu-ray Disc. The capacity of a piece of glass no bigger than a phone screen is capable of storing up to 50GB of data."We have developed a memory that can store data in a glass and has a long durability. This could be a form highly stable and safer than a portable memory," he added.

Beresna also asserted that when the device is very useful for an organization that has a large archive. The process of recording is done with a laser beam focused on a small footprint dots called 'voxels' into a pure silica glass. The process by which the polarization of light passing through layers of glass makes it look blurry. The data has been incorporated into the glass can be read using an optical detector.

The researchers have published findings in Scentific Journal of Applied Physics Letter, under the auspices of Lithuania Altechna companies to create technology that will be sold to international markets. (Tyo)
