Abstract

Magnetic heads on vcr drum are adjusted for protrusion, rotational angle, setting angle between two symmetrically positioned heads and height difference. Developed adjustment system covered assembly spec., namely ${\pm}2{\mu}m$ and ${\pm}30{\mu}m$ in rotational angle by using the image processing to determine head positions and S/W algorithm to compensate mechanical errors.
