摘要： PURPOSE:To make a titled device small in size and light in weight, and to drive stably an objective lens for concentrating the center of gravity of a movable part by installing focusing use and tracking use flat coils to both side faces and the upper face of an objective lens supporting member, and providing a magnetic field generating means. CONSTITUTION:Tracking T use coils 12a, 12b being flat in a square shape are installed to both side faces of an objective lens supporting member 2, and a focusing F use coil 13 which is flat in a square shape and whose both side edge parts are bent are installed to the upper face of the supporting member. When the coils 12a, 12b and 13 are brought to an electric conduction, an objective lens 1 supported by an F use spring 6 and a T use spring 8 is displaced in the F direction and the T direction by a magnetic field of a yoke 14 and magnets 15a, 15b. Since the coils 12a, 12b and 13 are fixed as one body to the supporting member 2, the center point of this force can be made to coincide easily with the center of gravity of a movable part, and since the magnetic field is generated in the plane orthogonal to the optical axis, a size of the optical axis direction can be made small, and the objective lens can be driven stably and with a high accuracy.

CONSTITUTION:An objective lens 1 is supported in the F direction and the T direction by focusing F use springs 6, 7 and tracking T use springs 9, 10, which are connected through a repeating member 8. An F use coil 15 and T use coils 16, 17 are installed to one face of a substrate 3, and the other face, respectively, and a thickness of the substrate is set so as to be equal to a difference between a distance extending from a lens supporting member 2 to a position of the center of gravity of the F operation, and its distance of the T operation. In this way, the position of the center of gravity of the F direction and the T direction is made to coincide with a point of application of force, the generation of a torsion resonance generated in the F use springs 6, 7 can be prevented effectively, and an exact follow-up operation can be executed. Also, the optical head can be made small in size since the space between the lens 1 and the repeating member 8 is utilized effectively.
