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.

You obviously don't do video editing.

or work with Virtual PCs/Virtual Machines....

I used to have multiple boxes to run multiple servers.... now most of my servers (file/Antivirus/dns/apps) run on a single powerful box running VMs....another box runs external stuff like mail and FTP.

the old boxes are my linux dev stuff.....nice to have.

Soo....anyhow....I welcome the higher densities....espeically in laptops. 100gb @ 7200rpm isn't cutting it anymore....bring on the 1.5TB x2 in raid 0! Make a laptop fly!

Of course, I'd rather see SDD than HD...access time is a killer for me...
