Abstract

PURPOSE:To erase accurately and securely data with an occurring error by making a data block length constant and by providing the 2nd erasing head closer to the leading part by the block length. CONSTITUTION:The fixed head is provided with erasing head E1, write head W and read head R and the 2nd erasing head E2 is provided one data block away from write or read head W or R to the leading part of a tape. Even if an error is found on the tape, the tape is advanced in the direction of write operation.
