摘要： In order to correct the change in the offset and amplitude of a tracking error signal because of the change in the position of an object lens from the center of an optical pickup, the offset amount and amplitude value of the tracking error signal with respect to the displacement amount of the object lens from the center of the optical pickup are checked beforehand, and the displacement amount of the object lens is estimated on the basis of a tracking correction signal by using an object lens displacement observer. An offset detection section and an amplitude detection section detect the offset amount and amplitude value of the tracking error signal respectively, and the tracking error signal is corrected by an offset correction circuit and an amplitude correction circuit on the basis of the offset amount and amplitude value having been checked beforehand so that the offset amount and the amplitude value of the tracking error signal become identical to those obtained when the displacement amount of the object lens is zero. In addition, the offset of the tilt error signal depending on the movement direction of the optical pickup 2 is detected and recorded beforehand, and the tilt error signal is corrected on the basis of the above-mentioned recorded offset when a rotation direction detection section detects the moving direction of the optical pickup.

摘要： A dust-screening member includes a plate-like light transmitting portion having a polygonal shape, and at least one plate-like side wall portion which tilts as much as a predetermined angle and extends from at least one side of the light transmitting portion so that they do not come in contact with each other. A vibrating member is fixed to one plate-like side wall portion and apples a vertical vibrational amplitude to the surface of the light transmitting portion. The light transmitting portion and the at least one side wall portion are formed to have a substantially uniform thickness by use of the same material. The light transmitting portion is positioned in front of an image forming element held by a holding member. The one side wall portion is fixed to the holding member at a position other than a position to which the vibrating member is fixed.
