Magnetic disk device and suspension having multiple arm portions of varying lengths
Embodiments of the invention suppress head jump at the time of application of an impact to provide for an excellent impact resistance performance in a magnetic disk device. In one embodiment, an actuator of a magnetic disk device comprises a suspension mounting the slider on a tip end side thereof to give a predetermined load to the slider, and an arm that holds the suspension, the arm being supported to be able to turn. The arm comprises two arm portions juxtaposed in a direction perpendicular to a surface of the disk, and a spacing between the two arm portions on a side of supported portions thereof in the direction perpendicular to the surface of the disk is larger than that on a side of the slider in the direction perpendicular to the surface of the disk.
