Ultrasound Waves Used To Increase Data Storage Capacity of Magnetic Media

Lucas123 writes “Electrical engineers at Oregon State University (OSU) said yesterday that they have found a technique to use high-frequency sound waves to improve magnetic data storage.The data write-technology breakthrough could allow greater amounts of data to be stored on both hard disk drives and NAND flash-based solid-state drives (SSDs), they said. Typically, when magnetic recording material is temporarily heated, even for an instant, it can become momentarily less stiff and more data can be stored at a particular spot. But, the technique has proven difficult to effectively increase capacity because heating tends to spread beyond where it is wanted and the technology involves complex integration of optics, electronics and magnetics, the researchers said. With the new technique, known as acoustic-assisted magnetic recording, ultrasound is directed at a highly specific location on the material while data is being stored, creating elasticity that allows “a tiny portion of the material to bend or stretch.” After the ultrasound is turned off, the material immediately returns to its original shape, but the data stored during the process remains in a dense form.” Read more of this story at Slashdot.

NVIDIA Tegra 4 processor details leaked: 4-plus-1 cores, 28nm, six times the power of Tegra 3

NVIDIA’s next superhero-themed mobile chipset has possibly made an early appearance in a leaked side in China, and it looks like it wants to go toe-to-toe with the latest processors from Samsung and Qualcomm. The Tegra 4 (codenamed Wayne) will apparently offer the same power-efficient 28nm process found on its Snapdragon rival and according to the slide from Chip Hell , there’s a dizzying 72-core graphics setup. That’s apparently 20 times the power found the Tegra 2 and six times that in the last-generation Tegra 3, which powered, among other devices, the Nexus 7 . Those graphics cores will be able to power screens up to 2,560 x 1600, with 1080p output at 120Hz, while the leak also mentions 4K — if only in passing. We won’t see any increase in CPU cores this time, with the same 4-plus-1 setup , but we are likely seeing a move to ARM’s latest design, the Cortex-A15 . It’ll also catch up with USB 3.0, being NVIDIA’s first mobile chip to do so, alongside dual-channel DDR3L memory. We’ve reached out to chipmaker and we’ll let you know when we hear more, but it’s highly likely we’ll be seeing this next-generation processor early next year — say, at a mobile trade show .

Autodesk University 2012: Zebra Imaging Demos Holographic Prints Via 123D Catch

Way back at AU 2009, Zebra Imaging’s holographic prints blew us (and you, judging by the hit counts) away. Here in 2012 they’re using Autodesk’s 123D Catch to capture footage for their jaw-dropping technology, like the nutty 3D family portrait you’ll see in this video: (more…)

Hands-On With Intel’s “Next Unit of Computing” Mini PC

crookedvulture writes “Intel’s Next Unit of Computing has finally made its way into the hands of reviewers. The final revision is a little different from the demo unit that made the rounds earlier this year, but the concept remains the same. Intel has crammed what are essentially ultrabook internals into a tiny box measuring 4″ x 4″ x 2″. A mobile Core i3 CPU provides the horsepower, and there’s a decent array of I/O ports: USB, HDMI, and Thunderbolt. Users can add their own memory, storage, and wireless card to the system, which will be sold without an OS for around $300. Those extras raise the total price, bringing the NUC closer to Mac Mini territory. The Apple system has a bigger footprint, but it also boasts a faster processer and the ability to accommodate notebook hard drives with higher storage capacities than the mSATA SSDs that are compatible with the NUC. If Intel can convince system builders to adopt the NUC, the future of the PC could be a lot smaller.” Read more of this story at Slashdot.
