Fujitsu announces technology for future hard drive capacity expansion

Fujitsu of America announced another advancement in its research of magnetic recording. Using patterned media technology, Fujitsu was able to achieve a one-dimensional array nanohole pattern with a 25 nanometer pitch. This process could one day enable one terabit per square inch recording on HDDs. Fujitsu also revealed a new development involving perpendicular magnetic recording read/write operation on random patterned media. With this technology, the soft underlayer is used as the PMR media, another important milestone.

A density of one terabit per square inch is about five times greater than the current drive technology on the market. Applying a one terabit areal density figure to today’s drive sizes would give us 3.5” drives capable of storing 5TB or 2.5” notebook drives holding 1.5TB.

Fujitsu first announced innovations with patterned media recording in June 2005. At that time, advancements were made with the introduction of a process to pre-pit aluminum media, resulting in nanoholes with an extremely dense and ordered structure. In addition, a technique called land/groove texturing allowed for the creation of discrete tracks in which the nanoholes could be formed. This progress in patterned media has enabled the development of high capacity hard disk drives, especially in smaller form factors.

This progress in patterned media recording closely follows the November 2006 Fujitsu announcement regarding the optical element being developed for thermal assisted recording, another promising advancement for future capacity increases.

Large 2.5 inch drives

Having Fujitsu provide high capacity drives also would benefit the consumer since now there would be 3 large drive (1+TB) manufacturers to choose from, when there was 2 (Seagate, Hitachi).

I have a 3.1TB fileserver that has a lot of unorganized files, that I would be able to copy onto an external 2.5" drive, plug it into my work pc and and find my down time more productive (for me at least). And reducing the number of drives from 12x3.5" to 3x2.5" drives would help on size/noise/head/power.

Your HDD's give out "head"? Lucky guy...

whoops, I meant "heat". I guess you can tell what 1/3 of my file server is for.
