Abstract
According to one embodiment, a magnetic disk device detects a first optimal fly amount, estimates a first optimal fly amount distribution, obtains a movable distance and an optimal moving speed of a magnetic head, detects a second optimal fly amount, moves the magnetic head to a plurality of movement positions specified based on the movable distance and the optimal moving speed while sequentially positioning thereat, and writes a plurality of spiral servo patterns to a magnetic disk while controlling the amount of protrusion of the magnetic head so that the spacing between the magnetic head at each of the movement positions and the magnetic disk becomes the first and second optimal fly amounts.
