Title: Magnetic recording medium
Inventor: OGIWARA HIDEO
IPC: G11B5/738
Filed: 2000-09-12
Abstract: PROBLEM TO BE SOLVED: To solve the problem that when only a granular soft magnetic film is used as a soft magnetic bed film in order to increase recording density of a perpendicular magnetic recording medium, magnetic domain walls are generated, thereby noise is generated due to shift and fluctuation of the magnetic domain walls to exert adverse influence on a recording pattern on an magnetic film of an upper layer and consequently a magnetic recording medium by which the adverse influence is eliminated and high density recording with low noise is enabled, is necessary. SOLUTION: The perpendicular magnetic recording medium has a substrate, at least one layer or above of bed film on the substrate and a magnetic film on the bed film. Further the soft magnetic bed film provided on the substrate has two-layer complex structure composed of an upper layer having granular structure in which soft magnetic metallic particles are dispersed in a nonmagnetic base material and a lower layer having continuous film structure.
