摘要： A magnetic recording medium (200) for communication with a transducer (220) moving relative to the recording medium along a line of relative transducer motion. The magnetic recording medium has a substrate (208) with a substrate surface (210), and a seed layer (206) on the substrate surface. The magnetic recording medium also has a soft magnetic underlayer (204) on the seed layer. The soft magnetic underlayer includes a magnetic material having a magnetic moment larger than 1.7 teslas. The soft magnetic underlayer has a texture that provides a magnetic easy axis that has an easy axis alignment parallel to the line of relative transducer motion. A magnetic storage layer (202) is on the soft magnetic underlayer.

摘要： Multilayer magnetic structures (20) comprising composite layers (22) and spacer layers (24) are disclosed. The composite layers (22) include a discontinuous magnetic phase (26) such as Co, Ni or Fe platelets, and a continuous nonmagnetic phase (28) such as C, AlO x, SiO x , ZrO x , Cu, Ag and Au. The spacer layers (24) may comprise Pt, Pd, Au or the like. The composite layers (22) and spacer layers (24) may be made by sputtering. The multilayer structures (20) are useful as magnetic recording layers of magnetic recording media (10). In one embodiment, the recording media (10) comprises a perpendicular magnetic recording medium including a substrate (12), a soft magnetic underlayer (14), a seed layer (16) and the multilayer structure (20).
摘要翻译：公开了包括复合层（22）和间隔层（24）的多层磁性结构（20）。复合层（22）包括诸如Co，Ni或Fe片晶的不连续磁性相（26）和诸如C，AlO x，SiO x，ZrO x，Cu，Ag和Au的连续非磁性相（28）。间隔层（24）可以包括Pt，Pd，Au等。复合层（22）和间隔层（24）可以通过溅射制成。多层结构（20）可用作磁记录介质（10）的磁记录层。在一个实施例中，记录介质（10）包括垂直磁记录介质，其包括基底（12），软磁性底层（14），种子层（16）和多层结构（20）。
