Abstract

PURPOSE: To prevent a magnetic head from shifting in position by providing a weight formed of an elastic material in a damper storage part provided to a swing arm.
CONSTITUTION: The damper storage part 21 where a damper 22 projected at the center part of a head arm 11 is formed in a nearly trapezoid shape. The damper 22 is formed of a rubber material, etc., having elastic action in a nearly trapezoid shape. Namely, the head arm 9 is provided with the damper 22 where the weight 23 is fixed and resonant vibration from a voice coil motor 12 and from outside is absorbed by the damper 22 and weight 23. Consequently, the positioning accuracy of the magnetic head 13 can securely be improved and the storage and reproduction characteristics of the magnetic disk 3 can be improved effectively.
