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
Sciaky, provider of electron-beam additive manufacturing (EBAM) services, will start selling these machines commercially in September. The company has used its EBAM 3D printing technology for making very large, high-value, metal prototypes and production parts for aerospace and defense OEMs.
At this year’s Google I/O, the spotlight was pointed on gender inequality in the high-tech industry. Google has established a new initiative that it hopes will even out the playing field, Made w/Code. Part of this initiative will fund free online courses in basic coding.
