HGST unites nanoimprints, self-assembling molecules to double hard drive space


Hard drive makers are in a race to boost capacities and keep spinning disks at least a beat ahead of flash drives on the value curve. We've seen some exotic developments as a result, but HGST wants to go the extra mile by relying on two breakthroughs at once. Its future storage primarily takes advantage of self-assembling polymer molecules that align themselves into rows. By first splitting the molecules into very small lines and then using an equally rare nanoimprinting technology to put them into circular tracks, HGST can create platters with a 10 nanometer-wide bit pattern that's twice as dense as current hard drives. The technique should hold up in the real world despite ditching typical photolithography, the company says: the nanoimprinting remains useful in the error-prone world of storage, and it should scale as the patterns get smaller. If only the drive designer had a roadmap -- while the company has a tendency to bring its research to market, the lack of a timetable hints that we won't see these nanoimprinted drives very soon.

LG’s first flexible OLED phone due before the year is out

LG plans to launch a flexible OLED smartphone before the end of the year, the company’s VP of mobile has confirmed, though it’s unclear to what extent the work-in-progress handset will actually flex. The OLED panel in question is the handiwork of LG Display according to VP of LG mobile Yoon Bu-hyun, the WSJ  reports, with the proposed device set to launch sometime in Q4. LG Display’s work on flexible OLEDs has been underway for some time, though the company’s efforts have perhaps been overshadowed somewhat by rival Samsung’s YOUM development. Last year, according to a Korea Times report, LG Display was preparing for

Flexible displays are the Future of IT Industry! A part from 4k and smart home appliances, the CES 2013 saw a lot of attention being drawn towards bendable, flexible displays. The elasticised display idea isn’t something new as we have seen hoards of device concepts being crafted around flexible, bendable and even foldable displays. These concept devices give us a futuristic feel, be it a flexible phone to be worn around the wrist or a phone that opens up to turn into a tablet or PSP-like device. But how far is this future? Nokia has been toying with the idea ever since we remember. The technology sounds very fascinating and the possibilities and the extent to which bendable displays could be used are vast and leave us spellbound. However, these have always been concepts and we haven’t seen any device materialise in the real world. There have been several technologies that were conceived in these years and all have been put to their practical use. But the bendable d

Xarius: Charge Your Mobile From Air

Xarius is a portable energy generator that allows to charge electrical appliances by the use of windpower in areas without electricity. Its lightweight and compact design makes the wind turbine to a perfect companion on backpacking trips with little luggage. It is composed of a foldable three-wing-system and an internal energy generator. The integrated rope makes it easy to adapt to any environment.Hooks are attached to both of its ends to tighten the rope and open the wings at the same time using the resulting tension. For convenient charging the battery is permanently installed, so that the electrical device can be charged inside the tent. The LED on the hook shows the current charge of battery. The pulsating orange indicates that the wind turbine has to recharge. Even at low wind speeds the blades begin to rotate autonomously.
