The present invention relates to an information playback apparatus, an information-recording method and an information-recording medium. For example, the present invention can be applied to an optical-disc drive and a magnetic-disc drive such as a hard-disc drive for recording video data. To be more specific, when playback data including a bit error difficult to correct is detected, or when a an access is made to a defective sector, recognizable dummy data is used as a substitute for the playback data supposed to be read out from the defective sector. As a result, error recovery processing can be carried out with a high degree of efficiency when priority is given to continuity of output data.
