    Abstract: 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.

    Abstract: An apparatus and method for frequency synchronization is proposed to obtain the pilot tones and evaluate the frequency offset and time offset for frequency synchronization. The frequency synchronization method has the following steps: filtering a baseband signal of a frequency correction burst by using multiple pre-filters; measuring the baseband signal and the signals output from the pre-filters to produce the first power value and the second power values respectively; normalizing the maximum second power value by using the first power value so as to produce the first detection value; using the samples of the baseband signal at different time points and a predetermined mathematical function to produce the second detection value; combining the first and second detection values to produce the third detection value; and using the third detection value to determine whether the frequency correction burst is received or not.
