Fujitsu says it has successfully demonstrated the ability to perform basic read/write capability of each individual nanohole of the patterned media using a typical flying head on a rotating disk. That breakthrough could lead the company to produce hard drives with storage capacities of up to 1.2TB on a two-platter, 2.5-in. drive as soon as 2010, noted Joel Hagberg, vice president of business development at Fujitsu Computer Products of America, a wholly owned subsidiary of Tokyo-based Fujitsu Ltd.
The construction of ideally ordered alumina nanohole patterned media was done through a collaboration between Fujitsu Computer Products of America, Yamagata Fujitsu Ltd. and Kanagawa Academy of Science and Technology. The achievement is published in the July online version of Applied Physics Letters.
"[Fujitsu's achievement] allows especially the smaller form factors to reach pretty high capacities. From a business-requirement standpoint, one advantage that brings is the opportunity to use smaller drives for applications, and smaller drives tend to use less power," remarked Rydning. "That kind of technology is definitely what's needed to get [improved storage] requirements."
