An optical recording medium, an apparatus for recording/reproducing data on/from the optical recording medium, a method of recording/reproducing data on/from the optical recording medium, and a computer-recordable recording medium, on which a program for executing the method is recorded, are provided. A lead-in area, a user data area, and a lead-out area are arranged on the optical recording medium. The user data area includes a defect list (DL) area, in which a DL, including information on defects that have occurred in the user data area, is recorded, and the lead-in area or the lead-out area includes a disc definition structure (DDS)/recording management data (RMD) area, in which a DDS, used for managing the optical recording medium, and RMD, used for managing a recording state of the optical recording medium, are recorded. Accordingly, it is possible to efficiently manage the storage capacity of a disc by effectively performing defect management on the disc.
