Abstract
In a magnetic tape winding system for winding a magnetic tape by a predetermined length around a small winding frame from a magnetic tape feed roll, the condition of winding of the magnetic tape around the small winding frame is detected, and the winding surface condition of the magnetic tape wound around the small winding frame is optically imaged at predetermined timing. The quality of the winding surface condition of the magnetic tape wound around the small winding frame is judged by a calculation processing of image signals obtained by the optical imaging. The speed of magnetic tape winding around the small winding frame is adjusted based on results of the judgment.
