Abstract:
Disclosed is an optical disc with a first area to store data for playback and that is reflective or opaque to visible light, and a second area that is transparent to visible light and includes first and second concentric rings. In one embodiment, a method of printing information on the optical disc includes: printing an inverse first text pattern in the first ring during a first printing on a first side, where the first text pattern is formed in reverse as viewed from the first side; printing a second text pattern in the second ring during a second printing on the first side, where the second text pattern is correctly visible from the first side; and printing, during the second printing, a first solid pattern to overlay at least a portion of the first text pattern, where the first text pattern is correctly visible as viewed from a second side.
