Abstract
On a replica substrate, a reflection layer, a first dielectric layermade of ZnS—SiO, a recording layermade of a phase change type recording material, and a second dielectric layermade of ZnS—SiOare successively formed. In addition, a reaction protection layermade of SiNor SiOis formed on the second dielectric layer. As a result, an information signal portionis composed. A light transmissivity sheet is formed through an adhesive layer so that the light transmissivity sheet coats an information signal portion. As a result, a light transmission layer is composed. When the reaction protection layeris not formed, a reaction protection resin layer made of an ultraviolet ray setting resin is formed so that the reaction protection resin layer coats the information signal portion
