Abstract
Each servo disk is formed by obtaining an angle from a stopper space obtained by moving an actuator, further obtaining a feed pitch angle for each cylinder by a prespecified number of cylinders from the angle, and writing servo data thereon according to the pitch angle, so that a feed pitch angle becomes larger in association with a wider space between the stoppers, with which a larger track pitch for each cylinder can be insured.
