Abstract : “We have developed an advanced barium ferrite tape with a magnetic particle volume of 1600nm3; a surface roughness Ra of 0.9nm, as determined by optical interferometry; a 10-point average roughness Rz of 27nm, as determined by atomic force microscopy, and a perpendicular squareness ratio of 0.87; the tape features a magnetic particulate coating medium enhanced by fine magnetic particle technology, surface profile design, and particle orientation control. In combination with advanced tape drive technologies, this tape demonstrated an areal density of 123 Gb/inch2, corresponding to a cartridge capacity of 220TB.“
