  • Patent number: 4653037
    Abstract: A magazine has a main compartment in which disc-holders each provided with a record disc, are supported one above another. The disc-holders can slide into and out of the main compartment through an open side-wall of the magazine. The magazine can be raised and lowered in a record-disc changer to bring a selected disc-holder within the main compartment to a predetermined level at which the selected holder can slide out of the magazine and subsequently back into the magazine. The magazine includes an additional compartment located above the main compartment and separated therefrom by a separation wall. The additional compartment is open at the upper side so that an additional disc-holder can be loaded into the additional compartment from above. This additional disc-holder can also slide into and out of the additional compartment through the open side wall of the magazine. The same mechanism which slides the disc holders located in the main compartment operates on the disc holder in the additional compartment.
