Abstract
One aspect of the embodiment utilizes a servo frame interval correction apparatus which includes a detection unit for detecting a first servo frame formed on said recording medium. The apparatus includes an acquiring unit acquiring a detection time interval between said first servo frame and a second servo frame detected subsequently to the first servo frame from a table storing a detection time interval between a specific servo frame and a servo frame detected subsequently to the specific servo frame. The apparatus includes a differential calculation unit calculating a differential between the detection time interval acquired by said acquiring unit and a reference time interval; and a correction unit correcting an estimated position of said second servo frame based on the differential calculated by said differential calculation unit.
