Abstract: Recording devices are often used to record discussions, conferences, meetings and the like. The recorded information is reviewed or processed afterwards for example in order to prepare minutes or notes. The known state of the art proposes to use devices comprising two receptacles for tapes. But this solution adds cost to the recording devices, which will not be accepted from all potential buyers as only a small number of the buyers will actually use this functionality.
