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