Reflection or absorption of light in the visual spectrum by the label material in the label material layer (8) is affectable by illuminating the label material according to a label pattern. Changing the reflection or absorption results in a local change of color. The contrast that is herewith applied to the label material layer (8) can be used for creating visual information, such as text or images for forming a label. Furthermore a device (52) is provided for applying a label to the laser entry side of an optical disc (3). The device (52) comprises means for producing a laser beam (21) for illuminating the label material layer (8) according to a label pattern.
