IBM and Fujifilm have increased their magnetic tape capacity to 580 terabytes

Magnetic tape is one of the oldest methods of data storage that is currently used by large companies and organizations to archive large amounts of information. Cheaper and easier to maintain magnetic tape has led companies such as IBM and Fujifilm to continue to develop prototypes with higher capacities.

The two companies recently managed to make a kind of magnetic tape with a capacity of 580 terabytes. This product uses a strip with a length of 1255 meters, which is an experimental type of strontium ferrite (SrFe). Approximately, the strontium ferrite strip has 27 times the surface density and 50 times the higher storage capacity compared to the LTO-8 used in current products.

In the development of the magnetic tape, the task of designing the material to make the tape with the mentioned surface density was the responsibility of Fujifilm engineers, and IBM, using its signal processing technology, helped to significantly optimize the process of writing and reading information. The accuracy of writing data on the new IBM and Fujifilm magnetic tape reaches 3.2 nanometers, which is a significant figure compared to previous models.

IBM claims that advances in technology used in the new magnetic stripe will lead to the production of models with a capacity of 175 zetabytes in 2025. Each zetabyte is equivalent to 1 billion terabytes or 1 trillion gigabytes. This technology will be used specifically in data centers to provide the necessary capacity to store large amounts of information.
