Recording system of digital magnetic tape

Abstract

Abstract PURPOSE: To simplify the processing at error detection and to reduce the product cost, by recording the error display block behind the data block recorded, when error is detected on the media recording the data. CONSTITUTION: The data written in magnetic tape is read in immediately with the read-in head, inputted to the error check circuit 19 via the read data reproducing circuit 20 and checked for the error. When the error is checked, the error display block forming circuit 16 forms and outputs the error display block, and it is modulated at the write data modulation circuit 17 and written in the magnetic tape. Further, after outputting the error display block, the write data control circuit 15 is constituted so that the same data block can again be outputted. Accordingly, the recording system of this magnetic tape can simplify the processing at error detection, the magnetic tape drive system is made in low cost, and the product cost can be reduced.
