Abstract

A technique for voice or other similar communication signal storage (such as recording) and forwarding (such as playback) enables simultaneous access to multiple users through use of first-in-first-out memories (FIFO), microprocessor-controlled to fill intermediate memory RAMs at irregular intervals and to transfer the contents thereof to main memory RAMs for ultimate segmented disc recording, with playback therefrom also microprocessor-controlled at irregular intervals to transfer back recorded data in block form through the main memory RAMs and appropriate intermediate memory RAMs and FIFO memories associated with an appropriate playback channel or user. The various data transfers are controlled to avoid delays in the played back messages, succeeding segments of data being transferred to intermediate memory RAMs by the time the transfer of the previous segment is complete, thereby insuring continuity of communication.
