Fujitsu Computer Products of America Inc. announced that it has achieved a one-dimensional array nanohole pattern with 25nm pitch via the use of patterned media technologya process that will enable 1terabit/inch?recording on HDDs in the future. The process was presented at the 10th Joint MMM/Intermag Conference on Jan. 9 in Maryland, United States.

The solution is the result of the joint work of Yamagata Fujitsu Ltd, Fujitsu Laboratories Ltd and Kanagawa Academy of Science and Technology. Moreover, this work on nanohole patterned media is supported by the "Research Program on Development of Innovative Technology" of the Japan Science and Technology Agency.

In June 2005, Fujitsu first announced innovations with patterned media recording. At that time, advancements were made with the introduction of a process to pre-pit aluminum media, giving nanoholes an extremely dense and ordered structure. Moreover, the land/groove texturing technique created discrete tracks in which the nanoholes are formed. This paved for the development of high capacity HDDs in smaller form factors.

Also during the MMM/Intermag conference, Fujitsu announced a new development regarding perpendicular magnetic recording (PMR) read/write operation on random patterned media, which allows the soft underlayer (SUL) to be used as the PMR media. This progress in patterned media recording follows Fujitsu's announcement in November 2006 regarding the optical element being developed for thermal assisted recording another area to be explored to further increase drive capacity.

"Fujitsu is proud of its technology leadership in the HDD industry and is very excited to report these latest results on patterned media recording," said Joel Hagberg, VP of marketing and business development, Fujitsu Computer Products of America. "In conjunction with our recent announcements on thermal assisted recording and the availability of our PMR hard disk drives, we are poised to meet the growing industry demand for ultra-high capacity, compact HDDs."
