Abstract
PURPOSE:To smoothly execute precise and delicate tracking control, etc., by realizing the displacement of a head in a minute unit without sacrificing a head access speed. CONSTITUTION:In case of erasing or reproducing information recorded on a recording medium, when a head carriage 300 is displaced in an area which leastwise includes one of the retention characteristic part and the shift characteristic part of a displacement conversion element 500 by controlling a driving source 400 with the aid of a control means 600, the head 200 displaced by the head carriage 300 makes erasing possible for the whole area enlarged more than a track to be erased at the time of erasing and makes a high accuracy on-track state to occure at the time of reproducing. In case of moving the head 200 between tracks, when the head carriage 300 is displaced in the area of the shift characteristic part of the displacement conversion element 500 by controlling the driving source 400 with the aid of the control means 600, the head 200 is immediately moved to a prescribed track.
