Researchers at Southampton University have devised a mode to twist light pass through a meth wafer so it can stash away and read 50 GB of datum in the same agency that fibre optic cable television does .
The process use minuscule dots call voxels etched in the molecular structure of pure silica glass that flex light to salt away information ( the light itself changes focus as it passes through one depend on thelight ’s polarisation preference . ) The information can then be wiped and rewritten by re - etching the voxels .
Glass has a lot of advantages over other non - fickle store . In special , it can resist temperature up to 1800F and , since the etching are located within the structure of the glass itself , the information lasts quite literally forever with no noticeable data degradation .
As enquiry team fellow member , Martynas Beresna , said :
We have developed this computer storage which means data point can be store on the field glass and last forever . It could become a very unchanging and good form of portable memory . It could be very useful for organisation with big archives . At the bit company have to back up their archive every five to ten years because strong - effort store has a relatively short life .
Other U.S.A. let in cheaper and more compact aesculapian imaging , exact handling of atom - sized objective , and even high - resolution imaging far beyond what we see today . Great , now I have to copy my CD’s — yet again — to a Modern format . But hey , should be the last meter , right ?
