Abstract

PURPOSE:To attain high speed access, small sized device, to thin the titled device and to reduce a cost by flowing a current to a feeding and tracking coil in a magnetic head so as to move an optical head moving part in a prescribed direction via an elastic arm. CONSTITUTION:In giving a control current to the feeding and tracking coil 13, the coil receives force in the radial direction of a disk (direction of arrow A) by the action of the magnetic field of a magnetic circuit 21 and a 2nd elastic arm 17 supporting an objective lens holder 10 via a 1st elastic arm 15 is bent and deformed, its tip is bent elastically in the radial direction of the disk and the holder 10 is driven in the radial direction of the disk. In giving a tracking control current to a coil 14, tracking drive is applied. Moreover, in giving a focusing control to the coil 14, vertical force is exerted to both side faces 14a in the tangential direction of the disk in the L-shaped coil 14, the tip of the arm 15 is moved vertically elastically, the objective lens 10 is moved vertically to apply focusing drive.
