Abstract
A method of marking an optical recording medium is provided. The method includes providing a curable material on a non-data surface of the optical recording medium. An energy source interacts with the curable material to form permanent text and/or images on the optical recording medium. The energy source includes a laser that produces energy at a frequency absorbed by the curable material. The method does not require specialized equipment and allows for increased amounts of information to be marked on the optical recording medium.
