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. Accordingly, optical disk reproduction and/or recording characteristics are improved by performing an optimal tracking servo adjustment operation according to the determined optical disk type. Further, if the type of the loaded optical disk is read-only, there is no time loss, thus allowing a swift reproduction operation, since unnecessary operations such as recording mode adjustment and gain adjustment of a digital recording signal processor are omitted.
