A transfer arm includes a magnet which can be placed in alignment with the spindle aperture of a recording disc. A spindle is mounted to a support at a stacking station for receiving the aperture of the disc on the transfer arm when the disc is released. The extended tip of the spindle includes a swivel member made of magnetic material which is placed in alignment with the disc aperture by the magnetic field produced by the magnet. The disc is then released from the arm at the stacking station and slips over the aligned swivel tip onto the spindle for stacking.
