摘要：
A recording medium for storing a data stream is comprised of first error correcting codes obtained by encoding first information, and second error correcting codes obtained by encoding second information, and synchronization signals. The first error correcting codes have a first correction capability. The second error correcting codes have a second correction capability higher than the first correction capability. In the data stream, the second error correcting codes and the synchronization signals alternatively interleave the first error correcting codes. The first and second error correcting codes are encoded using Reed-Solomon codes.
