A method for controlling the recording speed of a multi-layered optical disc divides a multi-layered optical disc into a plurality of zones with each zone having a corresponding recording speed. It is then determined which zones need the recording speed to be reduced according to the quality of the optical disc. When the optical drive records data onto an inferior quality zone, it reduces the recording speed to guarantee the reliability of recorded data and enhance recording quality. When the optical drive records data on the next recording layer and has passed the zone that corresponds to the inferior quality zone of the previous recording layer, it increases the recording speed. Thereby the method ensures both quality and efficiency. Furthermore, the recording speed of each subsequent zone of the next recording layer corresponds to the recording speed of each previous zone of the recording layer.
