Labeling an optical medium having a prelabeled or unlabelable region

摘要

A method (800) for locating a labelable region (106) on a surface (102) of an optical storage medium (100) including an unlabelable region (104). A laser beam (224) is impinged onto a location (120) on the surface (102) without marking the location (120). Laser energy reflected from the location (120) is detected. Based on the reflected laser energy, it is determined whether the location (120) is in a labelable region (106) markable by the laser energy or an unlabelable region (104) not markable by the laser energy.
