Abstract
A controller rotates, using a spindle motor, a first disk medium and at least one second disk medium in a state in which the first and second disk mediums are stacked. In this state, the controller controls a VCM on the basis of first head positioning information read by a first head from the first disk medium. As a result, a carriage that supports the first and second heads is driven to position the first and second heads in respective target radial positions on the first and second disk mediums. The controller causes the second head to write second head positioning information to the second disk medium, while changing the target radial position in increments of a predetermined pitch.
