PERPENDICULAR MAGNETIC RECORDING MEDIUM AND PRODUCTION METHOD THEREOF |
摘要 |
A perpendicular magnetic recording medium for use on a magnetic recording/reproducing apparatus which has a magnetic head for recording/reproduction includes a substrate, a magnetic recording layer having a perpendicular magnetic anisotropy, and a soft magnetic under layer interposed between the substrate and the magnetic recording layer. The soft magnetic under layer includes a mechanism for for suppressing a motion of domain walls of the soft magnetic under layer at least with respect to an external magnetic field which is smaller than a stray magnetic field in a vicinity of the magnetic head within the magnetic recording/reproducing apparatus. |
