Abstract
In a sector mark waiting state, when a sector mark detecting signal is input to a magnetic disk controller, the magnetic disk controller initiates a write operation of sector data on a magnetic disk. In a non-sector mark waiting state, when a sector mark detecting signal is input to the magnetic disk controller, the magnetic disk controller stops the write operation of sector data upon the magnetic disk being performed.
