NGen Hard Drives with storage in excess of 2000 GB
There is no limit to data we'd like to store in our computers, PDAs and other gadgets, but our dreams liquefy due to the irritating limit of the storing capacity of the device. Scientists are constantly working to that effect in nano labs and have come out with a patterned magnetic recording medium for hard drives that will increase your gigabits (billions) into terabits (trillions).
Computers have already surpassed the 'superparamagnetic limit' of the longitudinal magnetic recording on disks that limits the data density to 250 gigabits per square inch with the help of perpendicular recording systems that increases the density and memory to about 10 times.
But now researchers at the University of Houston has devised a new next generation data storage system based on patterned media on top of magnetic multilayers, as shown in the figure.
As per the physicists:
Magnetic multilayers such as cobalt and palladium exhibit very large and easily tunable vertical magnetic anisotropies, which makes them suitable for ultra-high-density magnetic recording applications.This multilayered pattern surpasses the superparamagnetic effect and have paved the path for the production of terabit-per-square-inch, not less than 20-40 terabit, recording in a couple of years.
