When it comes to cramming as much data as potential on a platter , laborious thrust manufacturers will apply every john in the Scripture to maximise electrical capacity . Including turning up the heat asTDK plan to do with a new techniquethat could deliver 40 terabyte hard crusade by 2020 .
In layperson ’s term , it ’s really easy to induce and reverse a magnetic field — which is how data is written and take in a hard ride — as the temperature increases . So TDK has developed a laser system to temporarily heat the area where information is being written , which in turning allow for them to squeeze more bits onto a phonograph record .
The breakthrough that made this novel feeler potential was the development of a optical maser , which TDK refers to as a approximate - field light generator , that make a electron beam that ’s just tens of millimicron wide — any large and you risk efface data around the area where it ’s being write . And for comparing , that beam ’s about 1/10 as wide-cut as the lasers used to read a Blu - ray record — so we ’re mouth earnestly petite .
The engineering could very well be the next bountiful leap involve to push hard drive capacities to the next level , and TDK is confident it could be implemented in commercial-grade products as early on as late 2015 . [ DigInfo TV ]
