An improved optical disk labeling device includes a label holding dock containing a holding portion and an optical disk holding dock slidable on the holding portion. The holding portion has downward and upward tracks. The downward and upward tracks have two ends forming a first anchor portion and a second anchor portion that communicate with each other. Through an actuation member the optical disk holding dock can be anchored at a first position to receive a first depressing force so that the actuation member is moved along the downward track to hold the optical disk holding dock at a second position. At the second position the optical disk holding dock can receive a second depressing force so that the actuation member slides along the upward track and allows the optical disk holding dock to return to the first position.
