发明名称 MAGNETIC RECORDING MEDIUM, ITS MANUFACTURING METHOD AND MAGNETIC RECORDING AND REPRODUCING DEVICE
摘要 PROBLEM TO BE SOLVED: To obtain a magnetic recording medium which has superior electromagnetic conversion characteristic and is suitable for high density recording. SOLUTION: The magnetic recording medium has at least an orientation adjusting layer, a non-magnetic base layer, a magnetic layer and a protective film in that order on a glass substrate having streaks on its surface. The orientation adjusting layer is formed to include one or more kinds of metals selected from Co, Ni and Fe and one or more kinds of metals selected from W, Mo, Ta and Nb. Moreover, the orientation adjusting layer is formed to include at least one alloy selected from a Co-W system alloy, a Co-Mo system alloy, a Co-Ta system alloy, a Co-Nb system alloy, a Ni-Ta system alloy, a Ni-Nb system alloy, an Fe-W system alloy, a Fe-Mo system alloy and a Fe-Nb system alloy.
