Hitachi has announced that it will develop a desktop hard drive that will be capable of storing a whopping 1 terabyte of data on to it.

The announcement comes as the company has worked out a way to store data in a more space effient method compared to current practice.

Currently data in hard drives is stored onto the top of a disc horizontally. The new method allows the data to be written vertically into the disc allowing much higher levels of storage.

According to research, current data storage methods are restricted to around 120Gb per inch squared before the space runs out. The new method with almost double this figure to 230Gb per inch squared.

In practice this means that any new storage device under the new system will be capable of storing almost twice the data in the same space.

Hitachi are planning to have drives commercially available by 2007 at the latest.
