Abstract: An apparatus and method for winding up a magnetic tape in a cassette comprises first and second conveyance devices. The first conveyance device receives a cassette case, in which magnetic tape has not yet been wound up, at a receiving position, conveys the cassette case to a wind-up waiting position, at which said first conveyance means device provides the cassette case to the second conveyance device, and returns to the receiving position in order to receive a new cassette case in which magnetic tape has not yet been wound up. The second conveyance device conveys the cassette case to a wind-up position at which a magnetic tape is wound up in the cassette case. The second conveyance device then conveys the cassette case, in which the magnetic tape has been wound up, to the wind-up waiting position.

Abstract: In a magnetic tape winding system, an end portion of a magnetic tape, which is cut after the magnetic tape is wound by a predetermined length from a magnetic tape feed roll to a first small wind-up frame, is joined with one end portion of a leader tape having the other end portion engaged with a second small wind-up frame by use of a joining tape. Immediately after the joining, the magnetic tape and the leader tape joined by the joining tape is rewound by a predetermined length around the second small wind-up frame, whereby slack of the tape between the first small wind-up frame and the second small wind-up frame is eliminated without causing the joining section of the magnetic tape with the leader tape to contact the magnetic tape surface at the outermost circumference of the magnetic tape roll wound around the first small wind-up frame.
