Advanced magnetic tape technology for linear tape systems: Barium ferrite technology beyond the limitation of metal particulate media

Development of advanced barium ferrite tape media

“…For tape media, particulate magnetic tapes have historically achieved increasing storage capacity per cartridge by reducing the magnetic particle volume to increase the areal recording density [6]. So far, iron-cobalt-based metal particles (MPs) have been widely used for magnetic tapes; however, it is difficult or almost impossible to reduce their particle volume without deteriorating their magnetic properties.…”
