Abstract
Errors in a first data signal of a first error correction code system in a reproduced signal are corrected to get first correction-resultant data. Errors in a second data signal of a second error correction code system in the reproduced signal are corrected to get second correction-resultant data. All address information pieces in the second correction-resultant data for every error correction block are subjected to error checks. When at least one of all the address information pieces is correct, a descramble initial value is set in response to the correct address information piece. When all the address information pieces are erroneous, a correct address information piece is estimated from an address information piece associated with a previous error correction block and the descramble initial value is set in response to the estimated correct address information piece. The first correction-resultant data are descrambled in response to the descramble initial value.
