APPARATUS FOR VARIABLY SELECTING THE CAPACITY OF A RECORDING MEDIUM IN A RECORDING SYSTEM ABSTRACT OF THE DISCLOSURE Apparatus is provided for use in a recording system wherein messages are recorded on a recording medium of fixed length, to variably select the recording capacity of the medium. An operator- controlled selector permits an operator to establish a preselected capacity which is equal to or less than the total capacity of the medium. Signals are produced when messages are recorded, and a counter counts these signals, thereby accumulating an indication of the amount of recording medium that has messages recorded thereon. In one embodiment, the signals that are counted are representative of incremental, lengths of the recording medium so that the accumulated indication in the counter represents the total length of recorded messages. A comparator compares the accumulated indication in the counter to the preselected capacity and, when the preselected capacity has been attained, a correspond- ing output signal is generated. This output signal is used to provide a perceptible indication that the preselected capacity of the recording medium has been attained and, in a preferred embodi- ment, also is used to replace the recording medium with a fresh recording medium. As one type of recording system wherein this apparatus finds ready application, a central dictation system has a central record/playback unit adapted to communicate individually with any one of plural remote dictate stations. The preselected capacity of the recording medium may be represented as a length of medium, such as a percentage of the maximum length or capacity thereof, or as a selected number of individually established communications, or seizures, between the central unit and the remote stations. -i-
