A recording medium for storing start position information for each zone, a
method of managing data using the information, and an apparatus for
recording the information and controlling recording and reproduction of
data based on the recorded information. In a disc having a plurality of
zones which form a group, and a spare area which is allocated at the
start portion or the end portion of the group for replacing defects, when
start logical sector numbers of each zone are changed by slipping
replacement during initialization or reinitialization, the information is
stored in the defect management area to thereby increase the
compatibility of the medium. In particular, by the method and apparatus
of managing data using information stored in a defect management area,
generation of errors is prevented in reading or writing due to the change
of a physical position of a real-recorded file which are caused by wrong
calculation of the start logical sector numbers for each zone.
