Fujitsu makes advancement in HDD storage density

Posted on Saturday, January 27 2007 @ 10:57:06 CET by

Earlier this month Seagate promised improvements in hard drive density and now Fujitsu does the same:
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.
