Mu00ecdia of storing information recording / playback apparatus, method of recording / reproduction, reproduction apparatus and data reproduction method of data. This is a storage media of information, a recording / playback apparatus, and a method of recording / reproduction that is provided for the improvement of efficiency of reproduction of the data.The apparatus for recording / playback includes: a recording unit for recording / reading of data on a storage media of information and for reading data from the media device; and a controller to control the recording unit for recording / reading a block of substituiu00e7 Will be overwritten logic (logical overwrite "- low) to update data stored in the media in a firstThe area of the media, to record a replacement block for replacement of a defective block generated in the media in a second area of the media.And for the recording of a second block replacement replacement by defect of a first block replacement in the second area if the defect is detected during the recording of the first block replacement in the first area to perform the logic of a block overwriting The original stored in a predetermined area of the media.Being generated an item of annotation list of defects (defect list "- DFL) including location information of the original block and location information of the second block replacement for indication of the state of replacement, and with a displacement of information located The first block of substitution in the second block replacement.As a result, an area for replacement by defect and an area for replacement by low are discriminated from each other, and an efficiency of reproduction of data can be improved through a gerenciarnento effective information even in the case of replacement The replacement by defect is due to a defect generated during the replacement by low.
