ABSTRACT:
A data reading unit reads inner offset data from an offset reading in an inner direction toward a center of a storage medium and outer offset data from an offset reading in an outer direction toward a circumference of the storage medium. A data comparing unit compares the inner offset data and the outer offset data read by the data reading unit. A data-output control unit that outputs the read-data when a result of comparison by the data comparing unit indicates that the inner offset data matches the outer offset data.
