Abstract
A fastening portion 1a of a plate spring 1 of a head unit H supported by a support member 12 and an arm portion 1d is pressed by a pressurizing pin 22a to impart the same displacement to a slider 4 as a Z-height when the head unit is mounted to an apparatus. In this condition, the inclination of the slider 4 is measured, and, further, the arm portion 1d is twisted by a tool 30 to correct deformation in the roll direction. Since the plate spring 1 is corrected in the same condition as when the unit is mounted to the apparatus, an accurate correcting operation is conducted.
