the amrket

Hitachi Global Storage Technologies have announced end-year launch of their hard drives based on perpendicular recording. Toshibha and Seagate have announced their plans to do the same.
Perpendicular recording is a new recording method that should companies to offer hard disks with much larger storage capacities.
Perpendicular recording is so named because the magnets in a disk drive are placed upright, and not end to end. The technology itself is not new - it has been around for 20 years - but its implementation in commercially available hard disk drives is.
Hitachi is currently testing sample perpendicular recording-based disk drives. the company expects that 1 terabyte (TB) hard disk drives or 20GB Microdrives by 2007. The company is currently field testing a 100GB, 2.5-inch drive based on an 80 gigabits per square inch version of the technology.
Toshiba is planning to introduce perpendicular-recording based 1.8-inch drives: a 40GB and an 80 TGB drive. The new perpendiculr drives will be quite similar to those used in the Apple IPod. Seagate plans to shipping its perpendiculr recording based drives later this year.
