Today, IBM Research, in collaboration with Sony Storage Media Solutions, has
announced that the two companies have created a tiny prototype storage cartridge that can store up to 330 terabytes of uncompressed data and still fit into the palm of your hand. The cartridge, called a sputtered magnetic tape, has an areal density of 201 gigabits per square inch, which is a world record and more than 20 times the density of commercial tape drives.
