Hitachi has announced that it has demonstrated the technical feasibility of magnetic recording at 610 Gbit/in2. While heads and media with an ultra-narrow track pitch of 65nm are still in development, these results indicate that current hard drive capacities can be increased by 2.5x.

Hitachi, Ltd. (NYSE:HIT / TSE: 6501) and Hitachi Global Storage Technologies (Hitachi GST), announced today that they have demonstrated the technical feasibility of magnetic recording at 610 Gbit/in2. This considerably exceeds the previously demonstrated capabilities of current perpendicular recording technology found in mass-production hard disk drive (HDD) products. These results hold the potential for a 2.5x increase in the storage capacities of current-generation HDDs.

Hitachi and Hitachi GST have together successfully verified an areal recording density of 610 Gbit/in2, using conventional perpendicular magnetic recording with continuous recording media and a software detection model. This achievement provides further evidence that hard drive capacities have the potential to advance at a rate of 40% annually. Application of this technology to future HDD products is expected to result in products that deliver larger capacities, smaller sizes and greater energy efficiency.
