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
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
