ABSTRACT:
According to one embodiment of the invention, a system for duplicating data is provided. The system includes a first recorder having an operating clock speed. An output port of the first recorder is permanently electrically coupled to an input port of a second recorder. The first recorder and the second recorder are coupled to a time code regenerator. The time code regenerator is operable to maintain a same operating clock speed as an operating clock speed of the first recorder and to provide to the second recorder a replacement time code for any time code that may not be communicated from the first recorder to the second recorder.
