概要
- 論文の詳細を見る
A lens actuator is an important mechanical–electrical component in optical pickup. For the high-sensitivity actuator used in a super-multi recorder, a novel magnetic circuit is proposed in this paper. This magnetic circuit consists of six thick permanent magnets with regulated placement, two thin permanent magnets, a base yoke, and an upper yoke. Experimental results verified the feasibility of the designed magnetic circuit.
