These days the main target of all the companies providing storage solutions is to increase the amount of data that can fit in the same space.
The crown for the above is held by Seagate but the company is developing more means to increase the data capacity so that it can retain the crown.
They are closer to fit in 1 terabit per square inch while they have set the goal to 50 terabits per square inch.
The goal can only be achieved by a technology called as HAMR or heat-assisted magnetic recording. The current disks hold 1 bit of information on 50 grains. These patches are irregularly shaped and to remain distinct each of the dots must occupy a certain area. This can be controlled by using the HAMR technique which makes it possible to have 1 bit of data on a single grain. That means fifty times the space.
Researchers have also stated that the disk sectors are becoming a thing of the past and they will soon be replaced by magnetic arrays. The incorporation of magnetic arrays will enable a 3.5-inch HDD to hold more than 300 terabits of data. They also commented that if everything goes as per plan then the technology can be made available before 2012.
