ABSTRACT:
A storage medium reproducing apparatus includes a storage unit, a correction history storage unit, a correction history implementing unit, and a correcting unit. The storage unit includes a plurality of information storage units storing information depending on whether a charge quantity is greater than a predetermined charge quantity threshold value, and a correction code storage unit storing error correction codes for the information stored in the information storage units. The correction history storage unit stores a correction history containing identification information for the information storage unit corrected with an error correction code is performed, and a content of the correction. The correction history implementing unit corrects information in compliance with the content of the correction when the information is read from the information storage unit. The correcting unit performs a correcting operation using an error correction code on the corrected information, and registers the correction history of the corrected information storage unit.
