<p>PROBLEM TO BE SOLVED: To eliminate a problem of curling by a simple structure. SOLUTION: Unit magnetic sheets s1 with magnetic recording sections 3 using magnetic strips on given sections are continued through folding and cutting-off perforations 4 as boundaries, and respective unit magnetic sheets s1 are folded zigzag and formed on the folding and cutting-off perforations 4, and thickness adjusting sections 2 are formed respectively on the inner central section sides on the two-piece side crossing orthogonally the perforations 4, and the thickness adjusting sections 2 are constituted by applying a coating liquid such as, for example, varnish or protrusions are formed by embossing to manufacture a suitable continuous magnetic sheet without the necessity of a special material.</p> |
