DISK UNIT AND DISK ARRAY APPARATUS

摘要

To reduce vibration in the rotation direction acting on the hard disk drive with a part of the hard disk drive as the rotation center. The disk unit comprises a hard disk drive comprising a drive mechanism which rotates and drives a plurality of disk media, an arm rotatably supported on a pivot and placed as movable in the rotation area of the disk media, and an actuator which performs positioning control of the magnetic head fixed to the arm to a target position on the disk media, a frame supporting the hard disk drive, and a dynamic absorber placed in the hard disk drive or in the frame, wherein the dynamic absorber absorbs vibration in the rotation direction acting on the hard disk drive with a part of the hard disk drive as the rotation center.
