ABSTRACT:
A recording medium for storing a data stream is comprised of first error correcting codes obtained by encoding first information, second error correcting codes obtained by encoding second information, and synchronization signals. In the data stream, the second error correcting codes and the synchronization signals alternatively interleave the first error correcting codes. The second error correcting codes have the same number of corrections as the first error correcting codes. A code length of the second error correcting codes is shorter than a code length of the first error correcting codes.
