Abstract

PURPOSE:To obtain a plurality of actuators capable of being positioned with a rockable shaft, lowered in height of a magnetic circuit forming unit and increased in the installation floor area thereof. CONSTITUTION:A yoke 10 consists of a rear surface yoke unit 11, one side surface yoke unit 2 laterally projected from one side of the yoke unit 11 and elevationally continued, other side surface yoke unit 12' projected in the same height positions in a plurality of upper and lower stages to form an E shape together with the yoke unit 12, and a center pole 13. At the side surface yokes 12, 12' are mounted permanent magnets 14, 14' and pole pieces 15, 15' having curved surfaces corresponding to the confronting curved surface of the center pole 13 bent in a circular arc shape. A head arm 19 rockable around a rockable shaft 20 as a center is secured to a coil bobbin 18 wound with a rockable coil 17 and supports at the other end a magnetic head 21.
