Magnetic head positioning apparatus using boundary line detecting method |
摘要 |
A magnetic head positioning apparatus for adjusting the position of a head member relative to its support member by determining the boundary lines for the edge portion of the head body and the center of the pivot in the support member. Luminance variations near the boundary line between areas different in light reflections are derivated so as to determine the position of the boundary line with a high accuracy at a distance shorter than the unit block pitch of the camera photodetectors used to detect the image of the head body and the support member.
