Disk vendors have a rough idea of how other to reach 10 TB drives within 10 years. But what about 2 years? Hitachi global storage technologies has announced that they have achieved 2 1/2 times the current commercial recording density in a laboratory demonstration.
What does that mean for you? How about a 1 TB 2 1/2 inch disk?
Multipronged approach To achieve vertical recording density of over 610 Gbit/per square inch the HGST engineers had to improve on existing technology. Current recording density is about 250 GB/per square inch.
In the laboratory demonstration the linear recording density is 1.6 million bits per inch and the track density is 381,000 tracks per inch. The read head has a width of 40 nm, a feature size smaller than Intel's latest CPU process technology.
Notable improvements that HGST made are:
The Storage Bits take Kudos to HGST for this demonstration. This technology will likely make its way into disks that you and I buy in 2-3 years.
These enhancements remind us that disk drive R&D continues to eke out significant density from a 50 year old technology.
Disk drives aren't dead yet. Of course, I hate the fact that this makes the 320 GB drive I put in my notebook today seem tiny.
Comments welcome, of course.
