Abstract
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. Signals, which are produced when messages are recorded, are counted to accumulate 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 represents the total length of recorded messages. A comparator compares the accumulated indication a preselected capacity and, when the preselected capacity has been attained, a corresponding output signal is generated. This output signal may be used to produce a perceptible indication and, in a preferred embodiment, may be used to replace the recording medium with a fresh recording medium. If this apparatus is used in a central dictation system having plural dictators, 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 each dictator.
