CoPrCr-SiO2 Longitudinal Media for the Next Generation Magnetic Tapes

Abstract

To improve recording density of magnetic tape systems, CoPtCr based sputtered media have been investigated, which achieved coercivity of 2600 Oe higher than conventional Co-CoO obliquely evaporated media. Recently, SiO<sub>2</sub> added CoPtCr granular media, which are largely researched for perpendicular recording media, have also showed beneficial effects… (More)
