PURPOSE:To easily adjust the relative position between a magnetic disk and a magnetic sensor by rotating a magnetic sensor around a center magnetic head and positioning it on magnetic tracks on both sides. CONSTITUTION:Three magnetic heads 15', 15'', and 15''' provided to the magnetic sensor 15 are arrayed on one straight line X-X prior to adjusting operation. The magnetic sensor 15 is adjusted by being moved in a radial direction of the 2nd magnetic disk 12 so that the 2nd center magnetic head 15'' is positioned on the 2nd magnetic track 12'', and the magnetic sensor 15 is rotated around the 2nd magnetic head 15'' to adjust the position relation between the 1st magnetic head 15' and the 3rd magnetic head 15''', and the 1st magnetic track 12' and the 3rd magnetic track 12'''.
