Abstract

PURPOSE: To avoid defective information processing by automatically identifying defective tapes, through the count of written-in error in tapes for a given value and record of the mark representing defect on the said tape.
CONSTITUTION: During the processing of one volume of magnetic tape, the number of occurrence of magnetic tape written-in error 1 is counted 5, and when this number exceeds a given value, the tape is automatically rewound 12 and the identification mark representing defect 31 is recorded 18 on the beginning end of the magnetic tape. Further, in case of read-in, if the mark 31 is detected 23, the result is informed to the upper rank unit through the terminal 24.
