发明名称 Apparatus and method for determining type of optical disk
摘要 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.
