Hitachi Eyes 1TB Desktop Drives

Hitachi Global Storage Technologies will later this year begin selling hard drives based on perpendicular recording, a yet-to-be commercialized recording method…Hitachi is due to announce Monday.

The company is already testing sample drives based on perpendicular recording and says the technology could allow for 1TB desktop drives or 20GB Microdrives in 2007.

Perpendicular recording is perhaps the most significant near-term step in the evolution of hard drive technology. The method is similar to the longitudinal recording used in today’s drives in that it relies on magnetically charged particles for data storage. In today’s drives, the north and south poles of the magnetic particles run parallel to the disc but in the new method they are arranged perpendicular to the disc, as the name suggests.

“Without [perpendicular recording], existing technology will stall at about 120- or 130 gigabits per square inch,” says John Best, chief technologist at Hitachi Global Storage Technologies. “Longitudinal recording is running into significant problems with bit size.”
