Abstract: The present invention relates to a method for servo-controlling when a reproduction is requested to a multi-session disk for non-real-time data or real-time data of audio or video stream. This servo-control method using the information of table of contents reads information of a table of contents written in a disk when a data-requesting command is received from a connected host; distinguishes the type of data recorded in a target location based on the read information of the table of contents; checks whether the distinguished type is corresponding to the command type; and re-sets or maintains current parameters for servo-control operation if the distinguished type is matched to the received command, so that a servo-control mechanism is adjusted to the type of the requested data before a pickup starts to move to the target location.
