Abstract
Apparatus in a remotely controlled telephone answering device providing an audio or voice message indicating the time elapsed or, alternatively, the amount of tape used in recording telephone messages. In one embodiment, the apparatus comprises a recording medium such as a magnetic tape having the positional information pre-recorded thereon in a first channel and having a second channel for recording telephone messages. A playback head having first and second magnetic transducers respectively aligned with the first and second channels is coupled to a playback amplifier through a head switching relay. The relay is remotely controlled to selectively couple the transducers, one at a time, to the playback amplifier for playing back the positional information and the recorded messages.
