New TDK technology allows 2 Terrabyte platters - in 2014

TDK has issued a press release in which it announces that due to a breakthrough of their R&D department the capacity of hard disk platters can be increased.  The researchers of the Japanese technology giant  have achieved a whopping  storage density of 1.5 Terrabit per square inch. This will allow hard disk manufacturers to create 1 Terrabyte platters for 2.5" HDDs and 2 TB platters for 3.5" HDDs. To achieve the increase data density the company is using a technology that goes by the name Heat Assisted Magnetic Recording (HAMR).

The technology works by heating the surface first with a laser before the bits are written to the disk, the heat should make it easier to write to the disk and after it cools down, the bits should be more stable. Due to the higher density the bits would normally become more unstable as they become so little that even a little bit of environmental warmth  could change their state. TDK also had to make improvements in the write/read head, but the company has not disclosed any information on what it did on those parts.

The technology will be demonstrated during Createc Japan 2012, the company expects that the new technology will become available in products in 2014.
