ABSTRACT:
A belt-like pattern reading unit reads a belt-like pattern given to the media storage cell using an image unit provided in a hold unit. A deflection amount calculating unit measures a deviation from a reference position of a horizontal pattern borderline corresponding to a position of the hold unit on a arm unit based on the read belt-like pattern, calculates a deflection amount of the arm unit based on the measured deviation, and stores a correction value of a position corresponding to the deflection amount in a correction value storing unit. A servo control unit controls movement of the hold unit using the correction value.
