Abstract
PURPOSE: To realize a writing of the servo information, by controlling the position of a magnetic head by meas of the head access mechanisms of both the magnetic head position detector and the magnetic disk device.
CONSTITUTION: The index signal is written previously before setting onto the upper surface of the lowest layer disk 3c among the magnetic disks 3aW3c. The magnetic heads 6aW6f are positioned by means of the exteral head position detector 18 and the head access mechanisms 11, 12 and 13 each. Then the reference signal is read as well as the index of the disk 3c by the heads 6e and 6f. These signals are then used as the standard to write the servo information onto the upper surface of the disk 3a through the head 6a.
