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
Machine vision and video streaming systems are used for a variety of purposes, and each has applications for which it is best suited. This denotes that there are differences between them, and these differences can be categorized as the type of lenses used, the resolution of imaging elements, and the underlying software used to interpret the data.
Comic books long have appealed to kids as a fun way to introduce reading and art without being overly didactic. Now a software engineer and project manager from Oklahoma thinks the medium can be used to get them interested in STEM careers.
