Abstract

PURPOSE: To enable to erase the data up to the error generating part in a short time with one erasing control, by providing the error position detecting means and making variable the erasing length according to the error generation position.
CONSTITUTION: When the data is written on tape, the write signal WR is fed to the 1st counter 1 for count-up operation, and the tape drive signal GO is generated from the driver 2 for write-in. In the 2nd counter 4, the count signal indicating the length of data erasion is generated and if any error is produced on the way of data write-in, the error signal ERR is delivered to the 1st counter 1, the 1st counter 1 stops the count-up operation and magnetic tape is stopped. Further, when the data erasing signal ERS is fed to the 1st counter 1 and the erasing head erases the part in error, the count value of the 1st counter 1 is zero, erasing the erasing length according to the position of error generation.
