PROBLEM TO BE SOLVED: To provide an optical disk device (optical disk reproduction part) having a means for correcting reproduction data even when a readout error occurred due to vibration generated from a speaker. SOLUTION: A control part of the optical disk device (optical disk reproduction part) performs the error detection for inputted and decoded digital data, and stores it when the error is detected (S1→S2→S3). When a plurality of detection signals are stored, the error occurrence period is detected from these error detection signals (S4→S5→S6) when the periodicity in the occurrences of the errors exists. Using the error occurrence period and the error occurrence timing, the data corresponding to the portions in which the errors are detected are deleted, from the decoded digital data, and corrected digital data in which the data that are precisely read out continue are generated and outputted (S7).
