Abstract: Apparatus (12) for delivering recorded messages to a person called on a telephone, for recording responses by the called person on magnetic tape and for moving a magnetic tape to a particular location to deliver a further recorded message, if necessary. The location of a prerecorded vocalization is known to a processor (54) via a digitally recorded tape track parallel to the vocal track. Apparatus (50) is disclosed for recording digital data on an audio tape recorder. Specifically, digital data is accurately recorded on tape by trilevel recording in which a signal being recorded returns to a datum level after each data word is communicated to the recorder. This overcomes tape recorder drift to a high or low binary level at the end of such a data word.
