Hitachi announced today that 20GB 2.5cm hard drives will be commercially available by the end of next year. This represents a "density breakthrough" which will allow much higher capacities than today's drive technology. Current micro-drives, such as the ones used in the iPod Mini, max out at 6GB. This new "perpendicular" recording technology would allow for a 20GB iPod Mini in 2007. Capacity of such micro drives are expected to reach 60GB within 5-7 years. The technology, of course, will also bring increased capacity desktop drives which could max out at one terabyte.
Hitachi Global Storage Technologies have developed a digital storage technology method that will create a record 1TB storage density on disk drives.
The process, known as perpendicular recording, places tiny magnetic ones and zeros, the basis for digital technology, upright instead of end to end, allowing them to be packed closer together.
The Hitachi storage development would allow PCs to store a trillion bytes of information.
Hitachi will make the announcement, one the magnetic storage industry has been waiting on for twenty years, on Monday
According to the New York Times, Hitachi plans to report a storage density of 230 billion bits per square inch. Such technology would create a desktop computer drive capable of storing twice the capacity of today's disks.
Currently the industry relies on updated improvements in end to end longitudinal recording systems. With the rate of improvement for such systems slowing down the storage industry is preparing to make the transition to perpendicular recording.
In a move that may keep costs down Toshiba and Seagate Technology will also be offering drives based on perpendicular recording this year.
sounds nice yes, but i rather want to see a revolution in quality on hitachi/ibm drives, their drives are the greatest crap since the dtla series hit the market
