摘要：
Perpendicular magnetic recording tape medium with laminated soft magnetic underlayers was successively formed on a 4.5 mu m thin plastic film by the facing targets sputtering method at room temperature. The tape medium showed extremely high SNR values with sharp transitions in playback tests by a drum tester, compared to a linear format commercial tape medium. An areal density of 45.0 Gb/in.(2) of perpendicular tape medium was confirmed by a high-resolution contact tester. These results suggest that the perpendicular recording tape medium by the facing targets sputtering method is a promising candidate for a tape cartridge of over 50-TB. (C) 2010 Elsevier B.V.
