An optical disc writer includes an optical pickup head and a supporting portion for supporting an optical disc having a central hole, an annular label zone and an annular control feature zone located therebetween. The optical pickup head includes a red light source, a blue light source, a red lens and a blue lens. The red light source emits a red laser beam penetrating through the red lens to write a label onto the annular label zone. The blue light source emits a blue laser beam penetrating through the blue lens, which is disposed between the central hole and the red lens, and travelling to the annular control feature zone. Thus, the optical pickup head reads information of the annular control feature zone and the red lens is moved to the annular label zone according to the information in order to write the label onto the corresponding annular label zone.
