Abstract

PURPOSE:To enable fast seeking operation and short-time settling operation by nearly equalizing rotary moment that a rotary actuator receives from an air flow on the surface of a disk between the outermost periphery and inner periphery of the disk. CONSTITUTION:The arm 4 of the actuator 3 rotates around the center point P of a rotary shaft 10 and a head 6 atop a support spring 5 moves between the OD track position and ID track position of the disk 1. When the center point P is set on the prolongation of a tangent 19 to the intermediate position MD between both track positions the angles theta1 and theta2' that straight lines 12 and 13' and tangents 14 and 15' contain are nearly equal and the rotary moment that the arm 4 receives becomes small. The angles theta are small and in the opposite directions, so the influence of force F between the head and disk is small and the fast seeking operation and short-time settling operation are enabled.
