A Study Of Tape Drive Using Ultrasonic Vibration Drum

Abstract

USV drum apparatus is shown in Fig. 1. In order to generate a traveling wave vibration on its surface, two standing wave vibrations In order to improve the trachng accuracy of the Vi! we have developed an USV (ultra-sonic vibration) drum that can drive tape directly on its surface. The Drum Piezoelectric Element settling time of the transient response was about 30 percent shorter than that of the
