ABSTRACT:
An optical disk is configured as comprising a pair of substrates one of which has a recording layer borne thereon, the substrates being joined together through an adhesive so that the recording layer is interposed therebetween. In one form, one of the substrates is of glass, the other substrate is of a resin. In another form, both the substrates are of glass or resin. Delamination is prevented by using the adhesive having a specific glass transition temperature, Young's modulus, and dynamic loss factor.
