Bp-06 development of barium ferrite tape media with high snr and thermal stability

The total volume of digital data is increasing at an explosive pace and is projected to reach 44 zetabytes (ZB) by 2020—10 times the volume of data estimated for 2013 [1]. Particulate media-based tape storage systems are widely used for data backup and archiving applications because of their low cost, stability of the recording media for long-term data retention, and the reliability of information retrieval and reproduction. Therefore, it is important to continuously increase the storage capacity of magnetic tapes. Achieving a higher areal recording density, requires the volume size of magnetic particles to be reduced. However it is a cause of deterioration of thermal stability. In this study, we investigated whether high thermal stability can be obtained with magnetic tapes in fine barium ferrite (BaFe) particles.
