摘要

Discs are stored in a circular holder. Three recordinger/ reproducers are arranged in the same plane as these, and the turntable can be positioned opposite any disc compartment and any of the processors. - While a first disc is read by one processor, a second fisc can be loaded into another processor for treatment immediately on completion of that of the first disc, which can then be returned to its compartment and replaced by a third disc without interruption of the process. The processors may be grouped together or distributed around the circle.
