HD Density Record by Fujitsu: 1TB per Squared Inch

Perpendicular recording has been the main recent technology breakthrough for HD system. If it will allow higher storage capacity, there are physical limits, and the only way to increase available space in the future will be via improved storage density. Here again, the current reading/writing magnetic heads of our HDs have to operate on a define area without modifying adjacent ones; and one can not minimize HD head at will.
Fujitsu scientists have achieved densities greater than the 1TB per squared inch theoretical maximum, by using a laser head. Its function is to modify the physical properties of the HD area to be targeted by the magnetic recording head. Due to the higher precision provided by the laser, one can then increase storage density over the 1TB/in2 limit.
One will have to see if in the future such technology is commercially viable ant technically reliable.
