RECORDING MEDIUM STORING START LOCATION INFORMATION PER ZONE AND METHOD FOR MANAGING DATA USING START LOCATION INFORMATION

摘要

A recording medium for storing start position information for each zone and a method for managing data using the information are disclosed. In a disc having a plurality of zones (201) which form a group, and a spare area (204) 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 for 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.
