| 摘要 |
A magnetooptical recording medium and a method for reproducing information from the medium wherein the medium includes a first magnetic layer which has in-plane magnetization at room temperature and vertical magnetization at an elevated temperature, a second magnetic layer for storing information which has vertical magnetization between room temperature and its Curie temperature, and a third magnetic layer disposed between the first and second magnetic layers and made of a magnetic phase transition material which undergoes a reversible change from antiferromagnetism to ferromagnetism at a phase transition temperature near the temperature at which the first magnetic layer changes from in-plane magnetization to vertical magnetization.
