Abstract(in English) | Amorphous RE-TM alloys, such as TbFeCo, are suitable for high-density magneticrecording because they are easy to provide with large perpendicular magnetic anisotropy. Weprepared magnetic recording media with these materials and tried to detect the leakage magnetic flux from this media as in the recent HDDs. As a writing method, we utilized the same method as used in MO drives. In consideration of magnetic properties of the media, it seems to be difficult toreconcile both the magneto-optical recording and the flux detection. We solved this problem byintroducing magnetic bilayer media. Playback resolution is much improved compared with opticaldetection and we are expecting that a much higher density than MO disks is feasible. |
