Displaying items by tag: MemoryNumberland engineering consultancy for new processes, new materials. New processes: We analyse, optimize and document processes often not covered by quality management handbooks and teach them to run. We translate technical demands into physical effects or properties and then find the suitable material.http://new-materials-broker.de/index.php/requests/itemlist/tag/Memory2016-07-29T20:05:47+02:00Joomla! - Open Source Content ManagementMagnetisation control by heat2016-01-16T20:59:30+01:002016-01-16T20:59:30+01:00http://new-materials-broker.de/index.php/get-in-contact/item/1530-magnetisation-control-by-heatAdministratorgrond@numberland.de<div class="K2FeedImage"><img src="http://new-materials-broker.de/media/k2/items/cache/f0c3a021df8a28f4e3936660c10f3aba_S.jpg" alt="Magnetisation control by heat" /></div><div class="K2FeedIntroText"><h1><span style="display: inline; float: none; position: static; font-size: 14px; font-weight: bold; font-family: Tahoma,Arial,sans-serif; font-size-adjust: none; font-style: normal; font-variant: normal; line-height: 14.3px; text-align: left; text-decoration: none; text-indent: 0px; text-shadow: none; text-transform: none; word-spacing: normal;">Magnetisation control by heat</span></h1> </div><div class="K2FeedFullText"> <p>ID: F1601-06</p> <p>A laser-induced pulse of temperature could allow the control of the magnetisation in the nanoscale recording news of hard drives. This astonishing effect could lead to much denser magnetic memories, providing an unprecedented scale of capacity development. Over the last many years, the magnetic disk storage space thickness – the number of bits of information stored per unit area – doubles around every 18 months. This trend is expected to carry on, showing the fast rate of technical progress in this area. However, larger storage space capacities must go hand in hand with the ability to read and write bits at smaller size scales. The next generation of disk read-and-write heads will utilize temperature to record information and shop data assisted by nanoscale antennas energised by semiconductor lasers that operate at high temperatures. Against this backdrop, a task is developing asers that can be integrated with magnetic recording technology and creating antennae to supply and focus the power on a range of a couple of tens of nanometres that causes the material to be heated. This heat-assisted magnetic recording (HAMR) approach will enable storage space densities of 1 terabit per square inch and beyond. So far, researchers have actually created innovative semiconductor lasers utilizing etching techniques to incorporate the laser mirror on a chip. Optimising the pattern transfer procedure ensures the smoothness of the mirror, ensuing in products with comparable performance to those perhaps not incorporated on a circuit.

The laser wafer that comprises numerous layers of materials with varying optical and electric properties features been modelled using device simulators. The layer compositions and depth are optimised for high-temperature operation through detailed simulations. Based on these designs, scientists have effectively prepared and characterised a new laser structure that demonstrated excellent overall performance in terms of production power at high operating conditions. This breakthrough technology revolutionises data storage by further pushing current capacity limits permitting the scaling of data storage in the ‘cloud’. Improvements in the storage technology should assist advance all kinds of information administration.</p> <p><a href="mailto:getincontact@numberland.com?subject=Get%20in%20Contact">getincontact@numberland.com</a></p> <p>&nbsp;</p></div><div class="K2FeedTags"><ul><li>Magnetisation</li><li>Control</li><li>Heat</li><li>Laser</li><li>Nano</li><li>Memory</li><li>circuit</li><ul></div><div class="K2FeedImage"><img src="http://new-materials-broker.de/media/k2/items/cache/f0c3a021df8a28f4e3936660c10f3aba_S.jpg" alt="Magnetisation control by heat" /></div><div class="K2FeedIntroText"><h1><span style="display: inline; float: none; position: static; font-size: 14px; font-weight: bold; font-family: Tahoma,Arial,sans-serif; font-size-adjust: none; font-style: normal; font-variant: normal; line-height: 14.3px; text-align: left; text-decoration: none; text-indent: 0px; text-shadow: none; text-transform: none; word-spacing: normal;">Magnetisation control by heat</span></h1> </div><div class="K2FeedFullText"> <p>ID: F1601-06</p> <p>A laser-induced pulse of temperature could allow the control of the magnetisation in the nanoscale recording news of hard drives.
