New Media Hero.Each year, IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries) researchers announce a break-through in areal density The number of bits per square inch of storage surface. It typically refers to disk drives, where the number of bits per inch (bpi) times the number of tracks per inch (tpi) yields the areal density. in the laboratory, but 1999 brought two: the 20.3Gbit/[in.sup.2] development, attributed largely to GMR (Giant Magnetoresistance) See magnetoresistance. head improvements; and a 35.3Gbit/[in.sup.2] development, reported in October. Here, though, the achievement was also attributed to a new formulation formulation /for·mu·la·tion/ (for?mu-la´shun) the act or product of formulating. American Law Institute Formulation of the recording media. John Best, vice president of technology at IBM's Storage Systems Division raised the possibility that it could be manufactured with existing commercial production equipment. "This proprietary magnetic material exhibits product quality stability, not the data-robbing fluctuations that had been feared to be present at such high densities," he said. "The test bits were as stable as those in products today." |
