Abstract
The precedingly reproduction signal reproduced by a precedingly reproducing head is recorded on a tape. If it is detected that the reproduction signal includes abnormality owing to a reason such as poor error rate, the recording operation is stopped. Then, for retrial of the recording, the information on the position where the abnormality has occurred is held. A memory may be provided to always rewrite and store the signal reproduced by the precedingly reproducing head, and also a simultaneously reproducing head which is different from the precedingly reproducing head may be provided to immediately monitor the recording state of the signal recorded on the tape. If it is detected that the signal reproduced by the simultaneously reproducing head includes abnormality, the recording operation is stopped, the information on the position where the abnormality has occurred is held. Further, the rewrite operation in the memory is stopped and the original precedingly reproduction signal corresponding to the signal to be recorded at the position where the abnormality has occurred is held in the memory.
