Density to be increased 7x per square inch.
While Hitachi has been claiming all the recent HDD plaudits for being the first company to crack the 1TB barrier Fujitsu has come up with a technological breakthrough that could have far greater significance long term.
The company claims it has created a method to increase the density of data stored on hard drives to 1Tb per square inch which is an incredible 7x greater than the best currently obtained by perpendicular technology.
It is achieved by the evolution of a process Fujitsu first announced in June 2005 called ‘patterned media’. In the company’s own words: “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 (now) allowed for the creation of discrete tracks in which the nanoholes could be formed.”
Taking away the PhD in this it roughly translates that Fujitsu has discovered a way to pack more miniaturised data closer together without corruption. The 1Tb per square inch capacity was achieved by reducing the size of each nanohole to 25nm, Fujitsu hopes to take this even further to 13nm which would result in 4Tb per square inch or 28x current data densities.
Sadly – as with many such ‘breakthrough’ announcements – consumer devices based on the technology won’t see the light of day for between two and three years, but what would be the fun of life if we didn’t wish away our youthful present for a technology riddled future when we’re old and wrinkly…?
