发明名称 Magnet used with an optical pickup actuator
摘要 Magnets, which have a surface facing a coil, through which current flows, generate magnetic flux to be emitted toward the coil in the direction of the normal line of the surface of the magnets toward the coil, the magnets having a recession or protrusion formed at the center thereof. The magnets form magnetic flux to be regularly generated and thus can generate uniform electromagnetic forces through interaction with current.
