An apparatus for winding magnetic tape into a cassette positions and holds a cassette case, extracts and retains leader tape, cuts and splices leader tape to magnetic tape, and winds magnetic tape onto a hub inside the cassette case. After a predetermined amount of magnetic tape has been wound on the hub, the magnetic tape is retained, cut, spliced to leader tape, and the extracted slack tape is wound into the cassette case. The tape retaining mechanism has a first and second tape retainer which separately hold the cut ends of leader tape, and a third tape retainer which holds the cut end of magnetic tape. The first and second tape retainers attach to the extracted leader tape, and are positioned with their attachment surfaces adjacent to an open guard panel of the cassette case. The tape retainer attachment surfaces hold tape in a manner that essentially closes the cassette case front cavity. Once the leader tape has been cut, either the first, the second, or both tape retainers are moved to separate the cut tape ends, but the new tape retainer attachment surface positions remain adjacent to the guard panel. In this way dust and foreign object contamination of the magnetic tape is minimized.
