Then these signals are reproduced to calculate asymmetry values(A1,A2). If difference(A1-A2) between both asymmetry values(A1,A2) is equal to or greater than a reference value of 0.05, it is judged that a method using the asymmetry values(A1,A2) is available for OPC(Optimum Power Control). If the difference(A1-A2) is less than a reference value of 0.05, it is judged that the method is not available. Then, the judgment result is recorded on the DVD-RW as a flag. A DVD drive judges whether the asymmetry values(A1,A2) are used for the OPC on the basis of the flag.
