DEFECT MANAGEMENT INFORMATION SETTING METHOD, RECORDING METHOD, DEFECT MANAGEMENT METHOD, PROGRAM, RECORDING MEDIUM, AND INFORMATION RECORDING DEVICE

摘要

An information recording device divides a data area into a plurality of partial areas (UDA1, UDA2) (step 303) and sets defect management information including a defect management method for each of the partial areas (step 305). The UDA1 is defined as an area where no defect management is performed while the UDA2 is defined as an area where defect management is performed. That is, information recorded in the UDA1 can have data continuity while information recorded in the UDA2 can have data reliability. Thus, a plurality of data having different uses and qualities can be appropriately recorded in the same information recording medium.
