Patent ID: 7127576

Claim:
A system for duplicating data, comprising: a first recorder having a data output port, an index data output port, and an operating clock speed; a time code regenerator having an input port and an output port, the time code regenerator permanently electrically coupled to the index data output port of the first recorder through the input port; a second recorder having a data input port and an index data input port, the second recorder permanently electrically coupled to the data output port of the first recorder through the data input port and permanently electrically coupled to the output port of the time code regenerator through the index data input port; wherein the first recorder is operable to receive a source tape storing data and a plurality of time codes indexing the data, transmit data and the time codes through the data output port and the index data output port, respectively, the time codes chronologically separated from one another by a time increment; wherein the time code regenerator is operable to maintain a same operating clock speed as the operating clock speed of the first recorder, receive the time codes from the first recorder through the input port, generate a replacement time code using the time increment to replace any time code that is not received from the first recorder, and transmit the received time codes and any generated replacement time code through the output port to the second recorder; and wherein the second recorder is operable to receive a target tape, receive data through the data input port, receive the time codes and any replacement time code through the index data input port, and record received data, the time codes, and the any replacement time code on the target tape.
