Abstract
PURPOSE:To realize driving coils and magnetic circuits, excellent in the rise-up characteristics of current, by a method wherein single stage or multi-stage coil rows, in which a plurality of driving coils, having a low inductance, are arranged in the same plane, are constituted to reduce electromagnetic connection between the coils. CONSTITUTION:Magnet assemblies 21, 22, in which 3 pieces of flat plate type permanent magnets are connected by the side surfaces thereof so that the front surface and the rear surface thereof are provided with reverse polarities alternately, are attached to the opposing surfaces of yokes 11, 12 provided opposingly to each other. Further, another magnet assembly 23 is provided between the magnet assemblies 21, 22 so as to keep predetermined gaps 31, 32. Driving coils 41, 42 are arranged in an upper stage and are pivoted in the gap 31 while the driving coils 43, 44 are arranged in a lower stage and are pivoted in the gap 32. The driving coils 41-44 are pivoted in the gaps 31, 32 having high flux densities by control current whereby a magnetic head, moved in conjunction with the coils, is positioned at a desired place.
