Title: Magneto-optical recording medium
Inventor: IKETANI NAOYASU
IPC: G11B11/105
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To solve such problems that when a magnetic domain is transferred and enlarged for reproducing, a large leaked magnetic field is required so as to stably transfer the domain from the recording layer but a small leaked magnetic field is preferable for enlarging. SOLUTION: The composition of the reproducing layer is varied between the recording layer side and the incident side of light in such a manner that the coercive force is low in the recording layer side and is high in the incident side. Since the coercive force in the recording layer side of the reproducing layer is low during transfer, the domain can be transferred with a small leaking magnetic field and a smaller reproducing magnetic field is required for enlarging, and therefore, good reproducing characteristics are obtained.
