<P>PROBLEM TO BE SOLVED: To solve the problem that a multilayer recording medium has a weak moisture resistance of a recording layer because a cover layer is less likely to adhere to an edge of a substrate and moisture is likely to enter from an outer circumferential part. <P>SOLUTION: The multilayer information recording medium has two or more information recording layers where an interlayer is formed between the information recording layers and the cover layer is formed on a top surface. The interlayer doesn't adhere to the edge of the substrate and the cover layer adheres to the edge of the substrate, thereby preventing the entry of moisture from the outer circumferential part. <P>COPYRIGHT: (C)2011,JPO&INPIT |
