Hitachi working on 5TB hard disk drives

Solid state disks are slowly gaining ground on traditional hard drives, particularly in laptops, but that isn�t stopping Hitachi from continuing to push HDDs to the limit. While recent developments in the field are already yielding one terabyte units, Hitachi believes they can have a commercial 3.5-inch hard drive on the market that can hold 5TB by 2010.

The company aims to achieve this boost in capacity with write heads that use something called current perpendicular-to-the-plane giant magnetoresistance (CPP-GMR), which pushed data density above one terabit per square inch. But it seems that Hitachi isn't the only one that is considering the release of a 5TB hard disk, Fujitsu also has some plans of their own – though fewer details on the technology used to achieve this have been made available.
