Abstract: In one embodiment, the recording medium includes a management area storing management information. The management information includes navigation information for reproducing data from the recording medium, and the navigation information including region information. The region information indicates at least one geographic region in which reproduction of the data is permitted.

Abstract: A method for determining type information of a recording medium, and a method and apparatus for recording/reproducing data in/from the recording medium using the method are disclosed. The method for determining type information of a recording medium includes the steps of: a) determining type information of a recording medium classified according to position information of a recording layer contained in the recording medium; and b) determining type information of at least two recording mediums having the same recording layer position on the basis of the presence or absence of a signal reflected from a specific area contained in a recording-medium inner side. Therefore, the method can be applied to a fabrication process of a new optical recording/reproducing device for a high-density recording medium, and can effectively record/reproduce data in/from the recording medium.

Abstract: A recording medium, a method for determining type information of a recording medium, and a method and apparatus for recording/reproducing data in/from the recording medium using the method are disclosed. The recording medium sequentially includes a lead-in area, a data area, and a lead-out area on the basis of an inner side. The data area and the lead-out area are designed to be read by a blue-ray optical beam. The lead-in area includes a first area readable by a red-ray optical beam and a second area readable by a blue-ray optical beam. Therefore, the recording medium can be applied to a fabrication process of a new optical recording/reproducing device for a high-density recording medium, and data can be effectively recorded/reproduced in/from the recording medium.
