Abstract: Disclosed is an apparatus and method for determining the type of an optical disk so as to implement an optimal servo operation according to the type of a loaded optical disk. In the method, the level of a wobble extraction signal is detected while a focusing servo is turned on, and the type of the loaded optical disk is determined based on the detected signal level, and then a tracking servo adjustment operation is performed according to the determined optical disk type.

Especially, the present invention can waveform-convert the waveform parameter for a multi-pulse portion of a multi-pulse writing waveform without changing its energy to produce an accurate waveform parameter.
