Five-dimensional data storage on glass Bashny.Net

 

Scientists from the Institute for the first time Southampton used nanostructured glass. In the experiment, they demonstrated record, which is due to femtosecond laser writing were able to obtain five-dimensional digital data. Storage means unprecedented options. The recording density of the data is 360 TB, if the temperature stability of more than thousand degrees Celsius. The media has an indefinite useful life.





The carrier itself carries the proud title of "the crystal memory of Superman", because "glass memory" is very reminiscent of the "crystal of memory" that is shown in films involving superheroes. Data is written due to the self-assembled nanostructures created in the quartz, they are able to store large amount of data about a million years.

Modern technologies are actively used for storage and transmission of data, whereby the people were able to find in the Internet the sites to communicate, work and play. For owners of resources in the Network to the colocation prices are quite reasonable, in return they get a stable job for their sites, operational data exchange and security.

Data encryption takes place by using five dimensions, including size and orientation. More than three hundred KB a digital copy of the file can be successfully recorded in 5D with ultra-fast laser. This laser produces extremely short, and most importantly, intense pulses of light. The file itself is written directly in three layers of nanostructured dots located from each other at a distance of about five micrometers.

Such self-assembled nanostructures change the way light passing directly through the glass, alter the polarization of light, which can be read by the combination of polarizer and optical microscope. A similar method is used in Polaroid glasses.

D. Zhang from the University of Southampton has been researching in the field of optical electronics, leading a joint project with the Technical Institute of Eindhoven. Jingu says that they were able to develop a fairly stable safe type of portable memory using glass. This method is very useful in organizations where there are large archives. Today, the company is trying to create a backup of its archives approximately every five years, as the memory from the hard drive itself is relatively short.
