ABSTRACT:
An object of the present invention is to provide a hard disk drive or related apparatus in which a possibility of head crash can be reduced to minimum even if the apparatus receives an external impact during the operating state. To achieve the object, according to the present invention, in a suspension including a load beam to which a magnetic head slider is to be attached and a head arm continuously joined to the load beam, a dummy weight is attached to the rear end of the head arm, and a attachment position of a joining member for joining a portion including the magnetic head slider, the load beam, the head arm and the dummy weight with a swing portion of a voice coil motor is provided at a position in the vicinity of the center of mass of that portion.
