A method for labeling an optical disc includes the following steps: receiving a command of a light scribe application program of a host to start labeling, reading an indication area of the optical disc to obtain information of labeling, transmitting the information of labeling to the host, and planning blocks capable of being labeled in the drawing area of the optical disc by the host. If planning the blocks capable of being labeled fails, labeling stops; and if planning the blocks capable of being labeled is successful, the drawing area of the optical disc is labeled, an indication is recorded at the indication area of the optical disc corresponding to the labeled block, and labeling then stops.
