Abstract
In a disc recording medium such as a Compact Disc capable of preventing occurrence of a burst error due to a scratch or a black spot on a disc in which the same data is repeatedly recorded for error correction, at least one adjusting section is inserted in an interval between repeatedly recorded same data. The length of the adjusting section is set to a value at which the same frames of at least two same data are not located in parallel to each other. Occurrence of a scratch will not prevent reading of the frame in at least one of the data.
