METHOD FOR IDENTIFYING LOCATION ON AN OPTICAL DISK

摘要

A method is disclosed for positioning an optical labeling mechanism substantially close to a particular track of a labeling surface on an optical disk, as shown in the flow chart. The method can include the operation of sampling a first texture of the optical disk at a first sample track location on the optical disk using an optical emitter and an optical detector, said optical emitter and optical detector being connected to a fine adjust sled, said fine adjust sled being slidably connected to a coarse adjust sled, as shown in block (210). A further operation can be moving the coarse adjust sled away from the first sample track location, as shown in block (220). Another operation can involve moving the fine adjust sled toward the first sample track location until the optical emitter is near the first sample track location, as shown in block (230). A further operation can be sampling a second texture of the optical disk at a second sample track location on the optical disk that is near the first sample track location, as shown in block (240). Another operation can involve comparing the first and second textures to determine if the optical emitter is substantially near the first sample track location, as shown in block (250).
