Abstract

12 PURPOSE:To facilitate the reduction of a thickness of an actuator and to enable to simply laminate multiple stages by composing the actuator of a magnetic circuit having a pair of flat plate yokes and two pairs of flat plate permanent magnets, and air gaps formed with the yokes and the magnets, and a rectangular coil engaged with the air gap. CONSTITUTION:A pair of flat plate yokes 15, 15' are formed to confront each other, a pair of permanent magnets 16, 17 and 16', 17' are disposed at the respective confronting surfaces, thereby forming a pair of air gaps 18, 19. The directions of the poles of these permanent magnets are vertical to the confronting surface, the directions of the magnets 16, 16' and 17, 17' are reverse to each other, as, for example, in the direction of arrows. An annular coil 14 of approximately rectangular shape is inserted into the air gap, and is engaged with the air gaps 18, 19, thereby generating drive force. In this manner, the thickness can be readily reduced, and a plurality of actuator assemblies can be laminated, thereby improving the through-put of a magnetic disc device.
