Hitachi has 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.

Hitachi will present its findings at The Magnetic Recording Conference (TMRC), taking place in Singapore from 29th to 31st , July 2008.

“These results are based on many years of experience with design optimization and material technology for perpendicular recording heads and media. We applied this knowledge to the development of heads and media with an ultra-narrow track pitch of 65nm, indispensable in achieving a recording density of 610 Gbit/in2. Development of iterative signal processing technology for high density recording further increased density and capacity,” said Hiroaki Odawara, Research Director, Storage Technology Research Center, Central Research Laboratory, Hitachi, Ltd.
