A reproduction apparatus includes a reproduction unit reading a reproduced signal of the data recorded on an optical disk, a reproduced signal processing unit performing ECC decoding for the reproduced signal using a predetermined parameter value, a storage unit storing the parameter number associated with the currently set parameter value and a parameter table listing parameter values and associated parameter numbers, and a control unit controlling the reproduction unit and the reproduced signal processing unit. The control unit, when ECC decoding fails, changes the parameter values in the order of the parameter numbers and controls the reproduced signal processing unit until ECC decoding succeeds in retried reproduction processing and, when ECC decoding succeeds, stores the parameter number associated with the currently set parameter value and sets in the next retried reproduction processing the parameter value associated with the stored parameter number in the reproduced signal processing unit. |
