1. A data recording method, comprising the steps of:
- encoding user data into first error correcting codes having a first correction capability;
encoding control information into second error correcting codes having a second correction capability higher than the first correction capability;
generating a data stream containing the first error correcting code, the second error correcting code, and synchronization signals, wherein the second error correcting codes and the synchronization signals alternatively interleave the first error correcting codes; and
recording the data stream.

2. A recording medium storing a data stream containing first error correcting codes obtained by encoding user data, second error correcting codes obtained by encoding control information, and synchronization signals, wherein:
- 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; and
in the data stream, the second error correcting codes and the synchronization signals alternatively interleave the first error correcting codes. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
