Using a specially designed optical element, Fujitsu was able to attain a spot size of 88nm x 60nm with 17% optical efficiency. In this optical element, a multi-layered structure with an optical transmission layer was adopted. Fujitsu is the world’s first company to achieve a sub-hundred nanometre optical spot with a layered optical element.
“This achievement realized by Fujitsu with the multi-layered optical element is an exciting milestone for high density recording development, as well as for the storage industry as a whole,” said Georg Dietsch, Director Storage Products Group EMEA. “With this accomplishment, Fujitsu is paving the way for HDD manufacturers to effectively meet the demands of PC and CE vendors for ultra-high capacity HDD products.”
In order to attain terabit class recording, a combination of leading-edge technologies are required, and Fujitsu remains at the forefront with such accomplishments. During 2005-06, several new breakthroughs were announced in Japan, including: advancements in patterned media technology (June ’05); a new lubricant that allows for lower flying height (April ’06); and improvements in head material development (August ’06). With this latest achievement in thermal assisted magnetic recording, Fujitsu continues to demonstrate its leadership in technological innovations designed to improve recording density.
Note: This optical element work has been done as a part of the "Terabyte optical storage technology" project of the Optoelectronic Industry and Technology Development Association (OITDA) and The Ministry of Economy Trade and Industry of Japan (METI) in 2002, and as a part of the project of The New Energy and Industrial Technology Development Organization (NEDO) and METI since 2003.
