摘要： Disclosed herein is a system for recording a marking in the readout area of an optical media, wherein the marking does not interfere, or substantially interfere, with the readout of data from the optical media. The system disclosed herein is supportive of commercial production requirements. Markings may contain content as desired by the user of the system, including text, graphics, or other items. The marking is formed in a photosensitive coating that is applied to the optical media, and then cured with a first light. A second light, having a substantially separate band of wavelengths from the first light, is used to image a marking into the coating. The coating is robust to many external influences, such as ambient environmental conditions, and physical wear.
