Abstract

PURPOSE:To achieve erasion of misinformation, and recording and rerecording of information only with forward operation, by providing an erasing head, write- in head, readout head and the 2nd erasing head toward tape run. CONSTITUTION:Toward the driving direction as the arrow or tape 4, an erasing head 1, write-in head 2, readout head 3 and the 2nd erasing head 6 are provided in the order. In detecting error of readout information after write-in during the write-in, the 2nd erasing head 6 after the read-in head 3 of a magnetic tape device is functioned, the erasion of error information is made during the forward run and the rewrite-in of the said error information is made with the head 2. At the end of rerecording operation, the misrecording information 5 is already erased at the erasing head 6 and recorded information 5' is information as a result of recorded information rewrite-in. Thus, without reversing for repositioning operation, the erasion, rewrite-in can be made easily with forward run.
