Title: Optical system driving device
Inventor: IKARI ICHIRO
IPC: G11B7/09
Filed: 1988-04-08
Abstract: PURPOSE:To reduce a cost and to obtain enough driving sensitivity in a tracking direction by making the width of a tracking coil in a driving direction smaller than the width of a magnet, which is arranged with facing to the tracking coil, and arranging the tracking coil in the almost center of the magnet. CONSTITUTION:When a current flows to a tracking coil 11, in a part 11a to face to a magnet 12, force in a direction I of the current and in a direction T, which is vertical to a direction B of a magnetic flux is generated by electro- magnetic operation. Here, in an upper surface 11b and a lower surface 11c of the tracking coil 11, the direction of the current and the direction of the magnetic flux are equal and the force is not generated. In a coil part 11d in an opposite side to face to the magnet 12, magnetic flux density is extremely small and electro-magnetic force goes to be extremely slight. Accordingly, to the tracking coil 11, driving force only in the operating direction T is operated. Further, since the tracking coil 11 is positioned in the almost center of the magnet 12, the large driving force can be obtained.
