Abstract
PURPOSE: To save the recording media by the recording of only the information at failure and its before and behind, by picking up it from the first recorder to the second recorder.
CONSTITUTION: The input information is continuously recorded on the magnetic disc 2 in revolution normally with the recording head 3, this information is reproduced with the reproducing head 4, and after that it is erased with the erase head 5. On the other hand, the amplitude of the input information is discriminated with the comparator 6, and the timer 7 starts the operation with the output of the comparator 6 at failure and the second recorder 8 records the information from the reproducing head 4. Since the recording head 3 and the reproducing head 4 are apart by a given distance, the information at normal state is recorded on the recorder 8 and the information after recovery from the failure is also recorded with the set time of the timer 7. Thus, the recording media can remarkably be saved by recording only the information at failure and its before and behind.
