ABSTRACT:
There is provided a magnetic tape device capable of highly accurate positioning at a high speed. For this purpose, the head is driven in the direction of the width of the tape by eliminating the friction between the tape the head. In order to allow positioning in the direction of the width of the tape, even if a servo signal cannot be read from a servo track, the absolute position of the head from a reference position is detected, and the head is controlled based on the absolute position.
