Abstract

The system provides an audio answer to an inquiry from a digital terminal such as a cardaphone, keyboard or a dial telephone. With multiple inquiry stations, the speed of memory reproduction is not audio speed limited, since the word messages from the message store are transmitted to the individual receiving terminals much above audio speeds.

Audio Message System

The system provides an audio answer to an inquiry from a digital terminal such as a cardaphone, keyboard or a dial telephone. With multiple inquiry stations, the speed of memory reproduction is not audio speed limited, since the word messages from the message store are transmitted to the individual receiving terminals much above audio speeds.

Drum 1 has prerecorded on it audio messages in a plurality of adjacent tracks. The desired message is selected by moving the head 2 to the desired track. During reading, the drum is driven at a high speed. This permits a rapid transfer of the selected audio message through amplifier 3 and multi-channel head switch 4 to a desired one of a number of rotating record-reproduce heads 5. The particular head chosen is determined by the position of switch 4. The heads 5 are carried on a drum 6 which rotates inside a portion of a loop of a magnetic tape belt 7. A common driving source drives the drum 1 at its high speed and the heads 5 and tape loop 7 at low speeds. The direction of movement of the heads 5 and tape loop 7 is opposed so that a resultant slow audio recording speed is obtained with the selected head recording the desired message in a chosen track of the tape loop.

This message is subsequently read from the tape 7 as it passes over a chosen one of a line of audio reproduce heads 8, amplified in a related read amplifier 10 and finally audio reproduced by a corresponding loud speaker 11. The message is...
