Patent ID: 8281226

Claim:
A reproduction apparatus comprising: a reproduction unit reading a reproduced signal of data recorded on an optical disk in units of recorded data; a reproduced signal processing unit performing ECC decoding for the reproduced signal using a predetermined parameter value set for the ECC decoding; a storage unit storing a parameter number associated with the currently set parameter value and a parameter table listing a plurality of parameter values and associated parameter numbers indicating an order of application of the parameter values; and a control unit controlling the reproduction unit and the reproduced signal processing unit; wherein the control unit, when the ECC decoding is not successfully completed, sequentially changes the parameter values in the order of the parameter numbers listed in the parameter table and controls the reproduced signal processing unit until the ECC decoding is successfully completed in retried reproduction processing and, when the ECC decoding is successfully completed, stores in the storage unit 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.
