ABSTRACT:
Disclosed is a magnetic tape system of the type where when a write error is caused by writing data in a magnetic tape by a magnetic head, the write error is processed according to the variable length erase method. In this magnetic tape system, when a write error occurs, a write retry operation is executed, and lengths of blocks erased by the write retry operation are integrated. When the integrated length exceeds a predetermined value, a tape error is reported, and information of a long IBG having a length exceeding the length specified by the ISO standard is prevented.
