Here's a development that will bring joy to those that prefer to hear mechanical noises from their hard discs instead of the inky silence of the new solid state drives. The current perpendicular magnetic recording technology used in today's hard discs are due to hit a brick wall within a couple of generations or so. This will finally give SSDs the chance to make mechanical drives obsolete once and for all when their capacities increase and the prices drop. To get around this, TDK intend to use lasers coupled with a high coercivity material to achieve this capacity improvement. The coercivity value of a material is a measure of how difficult it is to magnetize ie how strong the magnetizing field needs to be. A material with low coercivity, is easy to magnetize, but it can also lose its magnetic imprint (north and south domains) easily, especially with densely packed data and is easy to erase with stray magnetic fields and to some extent, physical shock. Conversely a material with a high coercivity value can be damned hard to magnetize, but will keep its magnetic imprint much more stably and crucially for data storage, can retain much smaller magnetic domains, giving rise to greatly increased storage capacity for all that ever increasing avalanche of crucial data, such as music files, dodgy videos and humungous video game installs.

At Interop Las Vegas 2009, HP and Microsoft today announced a four-year strategic global initiative to deliver an end-to-end unified communications and collaboration solution.

As part of their Frontline Partnership, the two companies expect to invest up to an additional $180 million in product development, professional services, as well as joint sales and marketing, to help organizations lower costs and improve productivity.

The solution, which is planned to span software, hardware, networking and services, would enable customers to improve business output and reduce travel, telecom and IT operating costs. This would be accomplished by streamlining communications across messaging, video and voice with connected applications and devices. HP and Microsoft also plan to provide the flexibility and control customers need to manage their communications infrastructure efficiently.
