ABSTRACT:
A method and apparatus for winding a magnetic tape on a reel. A magnetic field is applied along the width of the wound tape to pull the magnetic tape against a flange. Air is jetted between the tape layers at the point where the tape is wound so that the layers can more freely move relative to each other. Air pressure is reduced at another point around the wound tape so as to deplete the air so entrained between the layers.
