IBM expects that its new magnetic recording media with anti-ferromagnetically coupled (AFC) film will quadruple the data density of hard-disk drive products. "A primary limit to data density is the superparamagnetic effect," explains IBM's Currie Munce, a researcher, scientist, and director of advanced technology at IBM's Almaden Research Center. "As we make the magnetic grains on a disk smaller, we reach a limit when these small grains are susceptible to Brownian motion, causing the bits to flip." He points out that IBM's invention essentially makes the media "magnetically thinner." "AFC replaces a conventional single magnetic layer with two magnetic layers that are coupled with antiparallel magnetization," explains Munce. "The magnetic fields from the two magnetic layers that the recording head senses make the overall media thinner." Applications for the patent include server disk drives, desktop computers, and mobile and micro devices. For more information, call (408) 256-5530 or visit www.ibm.com
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
