METHOD OF AND APPARATUS FOR VOICE COMMUNICATION STORAGE AND FORWARDING WITH SIMULTANEOUS ACCESS TO MULTIPLE USERS ABSTRACT This technique for voice or other similar communi- cation signal storage (such as recording) and forward- ing (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 to main memory RAMs for ultimate disc recording, with playback therefrom microproces- sor-controlled at irregular intervals to transfer back recorded data blocks through the main memory RAMs and appropriate intermediate memory RAMs and FIFO memories associated with the appropriate playback channel or user; the various data transfers being controlled to avoid delays in the played back messages that are long enough to be perceived by the channel user, and with succeeding segments of data being transferred to intermediate memory RAMs by the time the transfer of the previous segment is complete, thereby to insure continuity of communication.
