Abstract

PURPOSE: To accurately position a magnetic head to the center of rotation of a rotary cylinder even if there is an error in machining by measuring the center position of the bearing part of the rotary cylinder and the inclination of its center axis, and adjusting the position of the magnetic head according to a calculated correcting quantity.
CONSTITUTION: Two noncontact displacement gauges 22 are inserted into the bearing part of the rotary cylinder 1 from above and below and the distances between the two displacement gauges 22 and 22 and the bearing part of the rotary cylinder 1 are measured over the entire circumference. Then the inclination of the bearing part center shaft of the rotary cylinder 1 to the rotary center shaft of a rotary mounting table 9 is calculated from variation in distance above and below the bearing part of the rotary cylinder 1, and the magnetic head 2 is shifted in position by the correcting quantity corresponding to the inclination of the shaft, thereby adjusting the magnetic head 2 to an accurate position according to the bearing part of the rotary cylinder 1 even if there is error in the machining as to the bearing part and outward shape of the rotary cylinder 1.
