When winding high performance magnetic tape onto a cassette it is essential that the tape be both accurately guided onto the reel and not be damaged. Accurate guiding requires edge guides along the guide path of the tape, and when the tape contacts the guides, damage to the edges of the tape can occur. This problem can be overcome by providing air bearings in the tape path which direct the tape through a curved path so that the tape acquires lateral edge stiffness and thereby is not subject to edge damage. As shown in the figure, tape 5 is fed through a tape cutter 6 to air bearings 1, 2 and 7. Air bearing 1 is retractably mounted. A vacuum tape disposal tube 4 is located opposite air bearing 1 to remove any unwanted tape from the tape path.
