Scientists at IBM and Sony have developed a new cartridge that stores 330 terabytes of data into a device the size of a human hand, setting a new world record. The first tapes had a storage capacity of only 2 MB.
The tape storage is now the most secure, energy efficient and cost effectivesolution for storing large amounts of archive data as well as applications such as Big Data and cloud computing, according to IBM.
Sony and IBM Research have developed a magnetic tape storage technology with the highest capacity of recording in areal density at 201GB data per square inch which is nearly 20 times more data than conventional tapes which store 9.6GB data per square inch. The goal of this drive was to backup data, maintain archives, and aid Sony entertained in storing different data resources.
The trick here is that IBM and Sony are using sputtered media made up of several layers of nano particles to extend tape length.
Most data centers rely on solid-state storage (SSD) drives for day-to-day storage because they are so much faster than tape drives at retrieving and storing data, but they are more expensive to acquire and maintain.
Within the past decade, IBM has managed to bump the aerial density from 6.67 gigabits/sq. inch (in 2006) to 201 gigabits/sq. inch. Regular tape uses a liquid magnetic layer which is easy to produce, making cartridges cheap and readily available. Sputtered tape does cost more to manufacture than current commercial tape but as demonstrated, its potential for very high capacity makes the cost per terabyte very attractive. Recent developments in the growing Internet of Things sector along with the popularization of cloud services have resulted in increased demand for high capacity data storage media.

A newly developed processing technology that reduces impurity gas is used in conjunction with sputter deposition, a method of forming a nano-grained magnetic layer with an average grain size of 7 nm, thereby resulting in extended tape length.
