Abstract
A method and device for searching a recording medium are provided. The recording medium has a management information area of which location information is overlapped with that of a program area. The method for determining an area on a recording medium having an overlapped time range between two areas reads a time address from a current position on the recording medium, obtains additional information from the recording medium or from a recording medium driving unit, if the read time address belongs to the overlapped range, and determines, based on the obtained additional information, to which one the areas the current position belongs. Therefore, it prevents wrong track jumps that are caused from time-overlapped areas on a capacity-expanded recording medium.
