Back in August of last year we reported on the research at TDK Corporation for a more efficient read head for mechanical harddrives. The technology would make it possible to create platters with 640GB capacity, which is considerably more than the 500GB platters we have to suffice with today. By using four platters, like the modern 2TB harddrives, you can achieve 2.5TB storage capacity, but with five platters you can build 3.5" harddrive with over 3TB of storage.

Back then it said that the technology would be commercially available in the beginning of 2010 and we can now confirm that the first harddrives using the technology are to be decided in March. it won't be until October/November that the majority of the harddrive makers are expected to let loose their 2.5TB models, and perhaps later on even 3TB+ harddrives.
Already this month TDK's more efficient storage technology will be brought into the 2.5" segment where new storage platters sporting 375GB capacity are getting ready for use by harddrive manufacturers.
