Researchers in Japan have reported success in an advanced data-storage technology that could help yield hard-disk drives with capacities of seven times or more than today’s most advanced drives in as soon as five years. Their work is a refinement of perpendicular storage technology, a method of data storage that is only just beginning to come into commercial use in hard-disk drives. The new research further increases the storage ability by organizing finer particles of magnetic material into a fixed, regular pattern. This discovery may open the way for 1Tb per square inch in density in perpendicular recording media. There are also several other technologies that need to be refined or developed before such can drives appear. The servo control technology that is responsible for moving the disk head across the media needs to be improved to work at finer steps, and the drive heads themselves need to be improved and better signal processing technology developed.
