<P>PROBLEM TO BE SOLVED: To provide a winding technology for stably winding a narrow long tape into an extremely long length reaching 10,000-30,000 m within the comparatively short setting of a winding width Lw of 25.5 mm, for instance. Ž<P>SOLUTION: A combination of tension T applied to the tape 3 and a winding speed S is appropriately controlled in winding. The winding tension is set such that a target value T<SB>0</SB>of initial setting satisfies an expression T<SB>0</SB>=T<SB>1</SB>(W<SB>1</SB>/W+C), and an intermediate target value T is set on the basis of satisfying an expression T=T<SB>0</SB>(1-L/50,000), wherein T1 (g/mm) is an appropriate tension when starting to wind a tape of 2.5 mm in width, W (mm) is a tape width, W<SB>1</SB>=2.5 mm, C=(W-W<SB>1</SB>)/W in the case of C=W<2.5 mm, C=0 in the case of W=2.5 mm, C=0.10-0.15 in the case of W>2.5 mm, and L (m) is a wound tape length. The winding speed is gradually reduced with the progress of winding. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
