Abstract

A colored optical disk and method for making the same are disclosed herein. The method comprises : disposing a first semi-reflective data layer (3) on a first resin layer, wherein the first resin layer has light transmission at a desired reading wavelength of greater than about 60% ; disposing a top side of a first fully reflective data layer (5) on a side of said first semi-reflective data layer (3) opposite said first resin layer, wherein reflectivity of the first fully reflective data layer (5) and the first semi-reflective data layer (3) is individually about 18 to about 30%, and wherein a difference in the reflectivity between the first fully reflective data layer (5) and the first semi-reflective data layer (3) is less than about 5% ; disposing a separating layer between said first fully reflective data layer (5) and said first semi-reflective data (3) layer ; disposing a second resin layer on a bottom side of said first fully reflective data layer (5) ; and adding color to at least portion of the optical disk.
