Advanced Barium Ferrite Tape Technologies

Barium ferrite tapes offer high capacity and long-term stability and are therefore set to replace the metal particulate tapes currently in widespread use. We recently developed an advanced barium ferrite magnetic tape medium that is more than comparable to the media to be used in the 128-TB cartridge expected to be launched in 2022 based on the 2012–2022 Roadmap from the Information Storage Industry Consortium. The limitations of enhancing the capacity by using metal particulate tapes are presented, followed by the details of the key features of advanced barium ferrite tapes, which include the mechanism for realizing high capacity with high reliability. In addition, the future prospects for tape media are discussed.
