Tape recording and/or reproducing apparatus with ultrasonically vibrated tape guides










Image Number 17 for United States Patent #5319506.

In an apparatus for recording and/or reproducing signals on a tape and which is selectively operative in a plurality of modes, such as, a normal recording or playback mode, a fast-forward mode, a re-wind mode and a jog mode; the tape is driven between supply and take-up reels at speeds characterizing the selected mode while being guided by a guide element which is ultrasonically vibrated for reducing the frictional resistance to movement of the tape, and the frequency and power of an ultrasonic drive signal employed for vibrating the guide element are controlled so as to obtain optimal reduction of the frictional resistance to movement of the tape while minimizing power consumption.
