PERPENDICULAR MAGNETIC RECORDING MEDIA |
摘要 |
A perpendicular magnetic recording medium having a perpendicular magnetic recording layer provided on a substrate and a soft underlayer formed between the substrate and the perpendicular magnetic recording layer. The soft underlayer includes a plurality of soft underlayers having different saturation magnetizations so as to improve signal-to-noise ratio, and at least one of the soft underlayers has a magnetization easy axis in a radial direction so as to improve transition noise. |
