公報）。However, the tape running is not constant in the forward and reverse running directions, and is largely influenced by the tape running system of the mechanism, such as the perpendicularity of the capstan and the pinch roller with respect to the substrate. Therefore, an azimuth adjustment mechanism for the magnetic head is required depending on the tape running direction, and several autoreverse azimuth adjustment mechanisms have been disclosed (for example, Japanese Utility Model Publication No. 15857/1983). .
