Magneto-optical recording medium and its manufacturing method

Abstract

In a manufacturing method of a magneto-optical recording medium formed by laminating a plurality of magnetic layers, there is provided a manufacturing method whereby at least two of the magnetic layers can be properly and individually formed by sputtering the same target means in the same vacuum vessel under different conditions at the time of a sputtering process in accordance with an element composition ratio and/or magnetic characteristics of each layer.

1 .- 8 . (canceled)  
   
   
       9 . A magneto-optical recording medium in which a recording film formed by laminating a plurality of magnetic layers is formed on one principal plane of a substrate, 
 wherein at least two of said plurality of magnetic layers consist of same component elements and have different element composition ratios and/or magnetic characteristics.    
   
   
       10 . A magneto-optical recording medium according to  claim 9 , where in a magnetic domain is enlarged and/or reduced by using temperature distribution of the recording film near a laser spot and a change in area of said magnetic domain is detected as information.  
   
   
       11 . A magneto-optical recording medium according to  claim 9 , wherein said at least two of said plurality of magnetic layers are continuously laminated.
