yahoo.cnet.com IBM experiment could lead to higher-capacity storage drives By Bloomberg News March 17, 2000, 9:05 a.m. PT ARMONK, N.Y.--IBM said it has discovered chemical reactions that may lead to the development of data-storage drives that hold 100 times more information than devices today. Researchers at IBM, the world's largest computer maker, found a way to chemically force tiny magnetic particles to automatically arrange themselves. In the arrangement, the particles, which could contain bits of information, could be packed together tightly and precisely. The discovery stems from IBM's research into "nanoscience," the study of matter the size of 40-billionths of an inch. The need for higher-capacity hard drives is increasing as companies and consumers look for ways to store reams of digital information, video and music. "This scientific discovery could lead to new solutions for storing the huge volumes of data generated worldwide," Currie Munce, IBM Research's director of storage systems and technology, said in a statement. In the IBM experiment, scientists put molecules containing iron and platinum into a heated solution. The molecules reacted with each other, forming into iron-platinum particles that are coated in a substance similar to olive oil. The particles are put on a surface and allowed to dry, which causes them to spread out in even rows, much like balls rolling on a floor. "Nature does (the even spacing) for free," said Dieter Weller, one of the researchers that discovered the reactions. Researchers put the particles into an oven and heated them for a half hour. The heat fixed the particles in place, coated them with carbon and made them magnetic. The magnetic particles could possibly hold data. Results from the work of the research team, which was led by Shouheng Sun and included Liesl Folks, Christopher Murray and Andreas Moser, will be published in tomorrow's issue of Science Magazine
