Abstract:
A system for recording a marking in the readout area of an optical media comprises a marking that does not interfere or substantially interfere, with the readout of data from the optical media. The marking is formed in the photosensitive coating (100) that is applied to the optical media (10), and then cured with a first light. A image of the marking is formed by exposing the coating a second light, having substantially separate band of wavelengths from the first light.
