<P>PROBLEM TO BE SOLVED: To provide an optical information recording medium which prevents deformation of a substrate and keeps good electrical characteristic by specifying relation between thickness and solidness of an intermediate layer. <P>SOLUTION: The optical information recording medium has at least the intermediate layer and a recording layer including dyes on the substrate. The intermediate layer meets the following condition (A). (Condition A): a 150 nm thick thin film is formed on the 380±25 μm thick Si substrate by using the same material as the intermediate layer. The maximum push-in depth when applying force of upto 0.5 mN at a constant speed for 20 seconds on the surface of the thin film by using an indenter made of a diamond square pyramid with a facing angle of 136° is defined as D(nm). When the thickness of the intermediate layer is defined as T(nm), N represented by an equation N=D/T is less than 2.0. <P>COPYRIGHT: (C)2008,JPO&INPIT |
