MAGNETIC DISK DEVICE AND DISTURBANCE COMPENSATION METHOD FOR DUAL-STAGE ACTUATOR |
摘要 |
A magnetic disk device according to one embodiment includes: a disturbance vibration detector; a movement position controller; and a disturbance compensation module. The disturbance vibration detector detects a disturbance vibration component with respect to a fine-movement actuator. The movement position controller drives each of the fine-movement actuator and a coarse-movement actuator to control a movement position of a magnetic head. The disturbance compensation module corrects the movement position so as to suppress the disturbance vibration component detected by the disturbance vibration detector. |
