Abstract
1332488 Recording and playback; digital data storage TELETYPE CORP 29 Dec 1970 [30 Dec 1969] 61502/70 Headings G4C and G5R Coded information pulses are recorded in precise positions on a record by using signals picked up from a clock track on the record, a delay signal being generated to stop the movement of the record before the next clock signal occurs. Whenever information is received by a storage register 50, a control 42 is activated to allow a motor 28 to drive a tape or disc record 23 through a clutch/brake unit 30. A clock pulse 84 thereupon picked up by a playback head 16 is fed to a control 70 which then causes the stored information to be passed to write amplifiers 52 and hence to recording heads 12, 14, 18, 20 for recording. The clock pulse also causes the control 70 to activate a delay timer 85 which, after the delay, causes the register 50 to clear, and also the control 42 to operate unit 30 to stop the record.
