MAGNETO-OPTICAL RECORDING MEDIUM AND METHOD OF MANUFACTURING THE SAME, SUBSTRATE FOR MAGNETO-OPTICAL RECORDING MEDIUM, AND MOTHER DIE STAMPER AND METHOD OF MANUFACTURING THE SAME

摘要

A magneto-optical recording medium (X1), comprising a laminated structure having a substrate (S1), a recording layer having vertical magnetic anisotropy and performing recording function, and at least one functional layer (12) positioned between the substrate and the recording layer. The surface of at least one of the substrate (S1) and the at least one of the functional layer (12) on the recording layer side includes fine recessed and projected surfaces (10b, 10c) having a surface roughness of 0.3 to 1.5 nm and a frequency of recesses and projections of 1 to 20 nm.
