<p>Optical disc (20) having high-contrast images (22) in the information area (25) and a method for creating such images. The optical disc includes an information area, wherein the information area is defined as an area capable of containing data readable by an optical disc player. Data is contained within the information area. An optically viewable high-contrast image is formed within the information area. The method may include providing a previously recorded master optical disc (60), including a disc substrate (62) and a photosensitive layer (64) thereon. A portion of the photosensitive layer may be removed down to the substrate within the information area of the master disc using a masking process (67) to form the high-contrast image.</p> |
