DISK DRIVE

摘要

A disk drive which suppresses undesired vibration caused by the imbalance of a disk that is loaded and transfers the disk at a high speed. The disk drive contains a plurality of balls (24) or a liquid (26) in a hollow annular portion (23) to constitute a balancer. The balancer rotates together with the disk to suppress vibration that generates when an imbalanced disk rotates at a high speed.
