IBM scientists have captured 330TB of uncompressed data into a tiny cartridge

In a new world record, scientists at IBM have captured 330 terabytes of uncompressed data — or the equivalent of 330 million books — into a cartridge that can fit into the palm of your hand. The record of 201 gigabits per square inch on prototype sputtered magnetic tape is more than 20 times the areal density currently used in commercial tape drives. Areal recording density is the amount of information that can be stored on a given area of surface. [1]
