PROBLEM TO BE SOLVED: To evaluate the information data read out of an assigned readout address of a data reproducing device by assigning the readout address recorded on an optical disk, by reading out and reproducing the information data a plurality of times, by comparing the information data read out of the assigned readout address, and by discriminating the presence or absence of the readout error of the information data. SOLUTION: The readout error of the information data is discriminated by assigning the readout address recorded on the optical disk, by reading out and reproducing the information data recorded on the optical disk a plurality of times, by comparing the address at which the information data is read out and the address at which the readout of the information data is assigned, by discriminating the error of the readout address, and by comparing various kinds of the reproduced information.
