An amorphous magnetic thin film (3) which is formed on a substrate (1) and has an axis of easy magnetization perpendicular to a film surface, wherein, when the composition of the magnetic thin film is represented by TbxDyy(Fe1-zCoz)1-(x+y) and when x, y and z are within ranges of 0 < x </= 0.12, 0 < y </= 0.12, and 0 < z </= 0.30, a condition to be satisfied by x and y is 0.25 </= x/(x+y). Consequently, an inexpensive magneto-optical recording medium with an improved C/N ratio is manufactured. <IMAGE> |
