ABSTRACT:
A method of fabricating a magnetooptic recording medium (10) having at least a reproducing layer (11) and a recording layer (13), from which information is read out by changing the state of magnetization of the reproducing layer (11) comprises steps of forming the reproducing layer (11) on a substrate (21), putting a high-density magnetic recording medium (30) storing information in a high-density magnetic pattern into close contact with the reproducing layer (11) to copy the high-density magnetic pattern formed on the high-density magnetic recording medium (30) into the reproducing layer (11), and forming the recording layer (13) over the reproducing layer (11) after copying the high-density magnetic pattern into the reproducing layer, to copy the high-density magnetic pattern into the recording layer (13).
