ABSTRACT:
Embodiments of the present invention provide a magnetic disk drive capable of easily suppressing degradation of position error caused by disturbance resulting from vibration from the outside. According to one embodiment, the magnetic disk drive acquires, during a period of time of track following control, data necessary for determining a filtering characteristic required to newly be specified in a peak filter; in association with the start of subsequent seek control, determines the filtering characteristic required to be specified in the peak filter; and specifies the determined filtering characteristic in the peak filter.
