Hitachi Global Storage Technologies says that its researchers have successfully shrunk the read head for hard drives by half, resulting in dramatically increased storage capacity that may herald four terabyte desktop drives by 2009.
The company announced the new nanometer recording technology at the Perpendicular Magnetic Recording Conference in Tokyo.
With the new, elegantly named current perpendicular-to-the-plane giant magneto-resistive heads (CPP-GMR heads to you laypeople), drive makers will be able to come out with 4 terabyte drives in 2011 and/or 1 terabyte notebook drives.
Where current drive heads can read media with tracks just 70 nanometers apart, a CPP-GMR head is able to do the same with tracks 50 nanometers apart or smaller. Indeed, 50 nanometer tracks are expected to hit the markets in 2009, and 30 nanometer tracks will arrive in 2011.
