A system, method, and medium for forming a visible label on an optical disc. Label data for a label track of the disc is received into a buffer of a disc drive. The label data is analyzed to identify the label track. A surface contour of the disc is mapped only near the label track. Focus actuator signals for the label track are derived using the surface contour. The label track is marked, with a laser of the disc drive, according to the label data while the laser is focusing the focus actuator signals.
