Abstract

PURPOSE: To prevent the cause of an error during a data block read when stopping a magnetic tape running at a high speed, by decelerating the speed of the tape down to a low speed and then by stopping the tape where its inter-block gap is positioned at a magnetic head position.
CONSTITUTION: Once an error of data block B is detected, controller 16' cuts off a driving signal to decelerate magnetic tape 7 and every time the data block is detected at the same time, block counter 17' counts up by one. Magnetic tape 7, decelerated down to a low speed, stops on the detection of inter-block gap. Then, the driving signal is turned ON to let the magnetic tape backward and at the same time, block counter 17' decreases its count value by one every time the data block is detected, so that when the count value reaches zero, magnetic tape controller 16' will cut off the driving signal after spacing by as many as data blocks. Next, data block B is read again. Thus, the cause of an error during the read can be prevented.
