Process and apparatus for marking and editing of elongated record carriers

摘要: A method and apparatus for marking a first elongated record carrier to facilitate its editing in conjunction with the of second carrier, two carriers bearing information that is be synchronously reproduced. The has both program signal control recorded thereon. conventionally used rate reproduction from during playback. physically marked humanly sensible form at precise intervals length predetermined relationship signals thereon thus correlating lengths without possible serious loss synchronization could otherwise easily occur due cumulative phase shift errors, etc. caused by indiscriminate splicing signal.
