Hitachi and Hitachi Global Storage Technologies announced they have developed the world’s smallest read-head technology for hard disk drives, which is expected to quadruple current storage capacity limits to four terabytes (TB) on a desktop hard drive and one TB on a notebook hard drive. <\/p>\n
Hitachi researchers have successfully cut down existing recording heads by more than half to achieve new heads in the 30-50 nanometer (nm) range, which is up to 2,000 times smaller than the width of an average human hair (approx. 70-100 microns). <\/p>\n
Called current perpendicular-to-the-plane giant magnetoresistive1 (CPP-GMR) heads, Hitachi’s new technology is expected to be implemented in shipping products in 2009 and reach its full potential in 2011. <\/p>\n
Hitachi will present these achievements at the 8th Perpendicular Magnetic Recording Conference (PMRC 2007) to be held October 15-17, 2007 at the Tokyo International Forum in Japan. <\/p>\n
“Hitachi continues to invest in deep research for the advancement of hard disk drives as we believe there is no other technology capable of providing the hard drive’s high-capacity, low-cost value for the foreseeable future,” said Hiroaki Odawara, Research Director, Storage Technology Research Center, Central Research Laboratory, Hitachi, Ltd. <\/p>\n
“This is an achievement for consumers as much as it is for Hitachi. It allows Hitachi to fuel the growth of the ‘Terabyte Era’ of storage, which we started, and gives consumers virtually limitless ability for storing their digital content.” <\/p>\n
Hitachi believes CPP-GMR heads will enable hard disk drive (HDD) recording densities of 500 gigabits per square inch (Gb\/sq. in.) to one terabit per square inch (Tb\/sq. in.), a quadrupling of today’s highest areal densities. <\/p>\n
Earlier this year, Hitachi GST delivered the industry’s first one-terabyte hard drive at 148 Gb\/; the company’s highest areal density shipping in products today is in the 200 Gb\/ range. These products use existing head technology, called TMR2 (tunnel-magnetoresistive) heads. <\/p>\n
The recording head and media are the two key technologies controlling the miniaturization evolution and the exponential capacity growth of the HDD. <\/p>\n
