Abstract
A control apparatus, storage apparatus and control method uses a correction value for head position written in a recording medium to control head position and prevents a use of a correction value that has improperly been read out. The apparatus comprises: an allowable range acquisition section that acquires a correction value allowable range which is a previously set allowable range of a correction value; and a head position control section that controls head position using a read out correction value in the case where the correction value that has been read out from the recording medium falls within the correction value allowable range acquired by the allowable range acquisition section.
