Abstract
A tape winding device in which magnetic tape is wound onto a reel. One or more magnets exert a magnetic force on the wound tape in a direction along the thickness of the tape, that is, along a diameter of the reel, in order to neatly wind the tape. The magnets may be movable radially to maximize the magnetic force or be moved axially to control the axial position of the tape independently of the reel flanges.
