Optical recording medium, apparatus for recording/reproducing data on/from optical recording medium, and method of recording/reproducing data on/from optical recording medium

摘要

An information recording medium, an apparatus recording/reproducing data on/from the information recording medium, a method of recording/reproducing data on/from the information recording medium, and a computer-recordable recording medium storing a program executing the method of recording/reproducing data from the information recording medium. A lead-in area, a data area, and a lead-out area are arranged on the information recording medium. The lead-in area or the lead-out area includes a disc definition structure (DDS)/recording management data (RMD) zone for recording information on defect management and recording management. In the DDS/RMD zone a DDS used for defect management and a RMD are written. The data area includes a spare area (SA)/defect list (DL) zone for recording replacement data that replaces defective data on the information recording medium and information on defects that have occurred on the information recording medium. A DDS/RMD block includes data area allocation information and initialization information used for managing the information recording medium and is recorded in a first recordable portion of the DDS/RMD zone. The data area allocation information includes location information of a DDS/RMD zone arranged in the data area and location information of the SA/DL zone. Accordingly, it is possible to efficiently manage the storage capacity of a disc by effectively performing defect management on the disc.
