Hitachi to Produce Terabyte Laptop HDD

Hitachi announced today it developed CPP-GMR, the world’s smallest read-head technology for hard 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 HDD.

“Researchers at Hitachi have successfully reduced existing recording heads by more than a factor of two 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). Called current perpendicular-to-the-plane giant magnetoresistive (CPP-GMR) heads, Hitachi’s new technology is expected to be implemented in shipping products in 2009 and reach its full potential in 2011”.

The 1,46TB and 1.2TB HDD capacities packed into laptop-use 2.5-inch form factor have been announced earlier by Seagate and Fujitsu.
