Title: Magneto-optical recording medium
Inventor: KASHIWAKURA AKIRA
IPC: G11B11/105
Filed: 2001-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical recording medium which is hardly affected by an unintended magnetic field from the outside and obtains a reproduced signal output sufficient to surely reproduce information. SOLUTION: The magneto-optical recording medium is provided with a reproducing layer 3, a first in-plane magnetized layer 4, a nonmagnetic layer 5, a second in-plane magnetized layer 6, and a recording layer 7. The Curie points of the first and second in-plane magnetized layers 4 and 6 are set to the critical temperature of the reproducing layer 3 or lower. Since a magnetized transition area 21 of the reproducing layer 3 is magnetized in the in-plane direction by in-plane magnetization of the first in-plane magnetized layer, a mask effect by in-plane magnetization of the reproducing layer 3 is enhanced, and magnetic domains 28 and 29 other than a magnetic domain 27 to be reproduced of the recording layer 7 are magnetically masked by the second in-plane magnetized layer 6.  This medium can be reproduced by the sufficient reproduced signal output regardless of the existence of an unintended magnetic field from the outside. Therefore the medium is preferable as a CAD type magneto-optical recording medium to which a magnetic field is not practically applied at the time of reproducing information.
