PURPOSE: To produce a planer multilayered recording material which induces significant magnetization perpendicular to the layers by forming recording layers and a single or multilayered film containing carbides, nitrides, etc., in a preferable order, number and thickness to have a desirable inner structure. CONSTITUTION: This recording material has such a preferable inner structure that a single or multilayered film (C) containing carbides, nitrides, oxides is formed on one or both surfaces of a recording layer (B) on a base body (A) in a preferable order, number and thickness. The recording layer (B) consists of an amorphous lanthanide transition metal alloy and can be changed by heat. Significant magnetization is induced perpendicular to the surface of the recording layer (B) to obtain a flat magneto-optical multilayered recording material. In this case, the layer (C) is formed as a layer C1 comprising plural components and having 30 to 500nm thickness. These components are made present in three or more element layers, carbide layers or nitride layers. The component of the element layers is selected from among B, Al, Ga, In, Si, Ge, Sn, Pb, Sb, Mg, Ti and Zr.
