Changer apparatus of the type having an input hopper for storing a plurality of recording media and an output hopper for storing recording media that have had messages recorded thereon by a recording deck. A movable withdrawing element withdraws a recording medium from the input hopper and transports it to a receiving device which operates to dispose that recording medium to the recording deck. The receiving device is further operable to remove the recording medium from the recording deck to the output hopper. A rotatable cam is drivingly coupled to the movable withdrawing element and includes a cam surface coupled to the receiving device whereby the receiving device is driven to remove one recording medium from the recording deck to the output hopper and then to receive the next recording medium from the withdrawing element to dispose that medium to the recording deck. Preferably, the withdrawing element takes the form of a pusher arm to push the bottommost recording medium from the input hopper to the receiving device; and the receiving device preferably is in the form of an elevator which lowers that recording medium onto the recording deck and then, after one or more messages have been recorded, lifts that recording medium to the bottom of the output hopper.
