Title: Magneto-optical recording medium
Inventor: SEKINE MASAKI
IPC: G11B11/105
Filed: 2000-08-10
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical recording medium in which extremely minute recording marks of <=0.2 μm size can be accurately formed. SOLUTION: In the magneto-optical recording medium for MAMMOS, the compositions of magnetic materials are controlled in such a manner that the magnetic material constituting a magnetic domain enlarging and reproducing layer has the compensation temperature higher than room temperature and has the Curie temperature Tcr lower than the Curie temperature Tcw of the magnetic material constituting a recording layer. Thereby, the saturation magnetization in the magnetic domain enlarging and reproducing layer disappears in the recording temperature region during recording information. As a result, minute marks as <=0.2 μm in size, for example, can be accurately formed in the recording layer.  Or by forming a leak magnetic field controlling layer having higher Curie temperature than that of the recording layer, changes in the leaked magnetic field of the recording layer with temperature can be suppressed to increase the power margin for reproducing light.
