み取るようにした光学式情報読取装置のトラッキングア
クチュエータにおいて、２極に着磁されたリング状のマ
グネットと、２個のコイルとをいずれか一方が回転自在
なるよう平面に対向して配置すると共に、光学ピックア
ップの光軸方向が上記の回転軸とほぼ直交するように配
置してなる光学式情報読取装置のトラッキングアクチュIn a tracking actuator for an optical information reading device that reads information recorded on a disk using an optical pickup, either one of a bipolar magnetized ring-shaped magnet and two coils is rotatable. A tracking actuator for an optical information reading device is arranged so as to face a plane such that the optical axis direction of the optical pickup is substantially orthogonal to the rotation axis.
