A magneto-optical recording medium comprising a transparent substrate, a first dielectric layer on the substrate, a magneto-optical recording layer on the first dielectric layer and a metal reflecting layer on the magneto-optical recording layer, optically with a second dielecric layer between the magneto-optical recording layer, wherein the magneto-optical recording layer has a Curie temperature Tc of from 100 DEG C to 200 DEG C and a layer thickness of from 15 nm to 60 nm, the metal reflecting layer has a layer thickness of not less than 60 nm and a product lambda d of a thermal conductivity lambda by the layer thickness d of from 2.5 mu W/K to 20 mu W/K, and the following formula is satisfied: Tc </= -10 x lambda d + 300. This magneto-optical recording medium has an improved stability under repeated recording and erasing, or continuous erasing, operations without a loss of a high recording sensitivity thereof. <IMAGE> |
