The last technology transition, perpendicular recording, improved areal density by arranging the bits in a perpendicular fashion, thereby enabling narrower data tracks and read/write heads.
Seagate began shipping today's highest areal density disk in September 2011.
Using perpendicular recording, scientists believe that the effects of superparamagnetism can be further forestalled, which would create opportunities for continued robust growth in areal density at a rate of about 40 percent each year.
Toshiba's 240GB MK2431GAH and 120GB MK1231GAL achieve an areal density of 344 gigabits per square inch (531.
Tape is indeed fortunate that magnetic disk has already demonstrated solutions to high areal density magnetic recording while being able to leverage that for higher volumetric densities.

Ed Grochowski, Executive Director, IDEMA USA, commented, "Today PMR has become a fully applied technology, responsible for the areal density growth in leading edge disk drive products.
One way to increase storage capacity is to increase the areal density of the medium.
As the areal density growth rate of current longitudinal recording begins to slow, perpendicular recording appears best-positioned to keep pace with the world's growing data storage needs, with the potential for far higher density levels over time than what could otherwise be achieved.
