FIELD: engineering of data carriers, methods for controlling data and engineering of devices for controlling data for recording and/or reproducing content from disk.
SUBSTANCE: data carrier consists of large amount of zones for controlling defects. Aforementioned large number of zones forms a group, backup area for replacing group defects is also provided, and information about source position for each zone is stored in certain area. Also, data control method is provided for recording and reproducing device, wherein large number of zones forms a group for controlling disk defects, backup area for replacing group defects is positioned, and in certain area information about source position for each zone is positioned, including following stages: reading information from source position, which is stored in certain area, for each zone, and access to data on basis of read information about source position and reproducing selected data. Also provided is data control method for recording and reproducing devices, wherein large number of zones form a group for controlling disk defects, backup area for replacing group defects is positioned, and information about source position for each zone is stored in certain area, including following stages: reading information about source position for each zone, which is stored in defect control area, calculating information about source position for each zone on basis of information about list of main defects, and realization of reading and recording of data when read information about source position is analogical to read information about source position.
EFFECT: decreased damage to data occurring due to errors in calculation of source logical sector number by recording and/or reproducing devices different from each other.
