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
Being in an incubator can be analogous to shopping in a “big box retailer.” You can find many things you need under one roof along with moral support to sustain and move your startup to a successful launch.
Scientists at four major universities in Europe have released a joint paper describing the use of light to put active materials into motion and to control that motion, producing lifelike mechanisms that may or may not contain living organisms, but can produce useful work.
