Fujitsu is going to announce a new storage breakthrough which may lead to notebook hard drives with a capacity of 1.2TB by 2010.
The company is announcing later this week that it has created ideally "ordered" alumina nanohole patterns for isolated bit-by-bit recording on a large disk area.
With that feat, 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.
The patterned alumina nanohole media was created via a Perpendicular Magnetic Recording (PMR) processes using nano-imprint lithography (enabling discrete distance from bit to bit or track to track), anodic oxidation and cobalt electrodeposition at a density of 100-nanometer-pitch nanoholes suitable to existing head technology.
