Magneto-optical method and apparatus for recording/reproducing data |
摘要 |
When data are thermo-magnetically recorded to a perpendicular magnetized film of a recording medium, it is possible to prevent unnecessary magnetic domains from being formed and unerasable magnetic domains from being produced. The medium 11 is rotated by a motor 12. When being passed through a recording field generated by a magnet 14, the medium 11 is irradiated with a recording beam generated by an optical head 13, so that data can be recorded to a perpendicular magnetized film of the medium 11 as bubble magnetic domains. Further, when the medium 11 passes through a correcting magnetic field generated by a magnet 15 disposed away from the position at which data are recorded, unnecessary and/or unerasable domains can be eliminated.
