Sony and IBM (IBM Research in Zurich in particular) announced that they achieved a record of data storage in a magnetic tape at 201 Gb / in² (gigabytes per square inch).
As stated in the relevant Sony announcement, this achievement has been made possible by combining Sony’s new magnetic tape technology —which uses a special lubricant— with a range of IBM Research technologies; such as recording/reading heads, motor control technologies and cutting-edge processing algorithms signals.
According to the announcement, the specific recording density in the space is about 20 times that of conventional magnetic tape storage media (9.6 Gb / in²). The result is a technology that allows storage level of 330 terabytes per data cartridge, while at present, data only 15TB can be stored.
In recent years, developments in “Internet of Things”, “cloud” services and “big data” have helped create new markets, resulting in increased demand for high capacity storage media.
In this respect, the magnetic tape is promising, as it allows data storage for long periods, low energy consumption, low cost and space saving. The key to the development of this technology is to reduce the distance between the magnetic strip and the magnetic head as well as to reduce the friction; something that has been achieved thanks to the use of the special lubricant developed by Sony.
As noted in the corresponding announcement from IBM, magnetic tape storage technology is experiencing a rebirth beyond its traditional applications; such as keeping video files, etc.
The two companies will rely on these new developments to further develop magnetic tape technologies, aiming at the commercial exploitation of next-generation storage media with even greater potential.
