    • An ultrasonic diagnostic apparatus is disclosed which can reduce the device amount of a receiving circuit, while obtaining the shape of an excellent received beam. In this ultrasonic diagnostic apparatus, a plurality of transducer elements are arrayed and used as an ultrasonic probe, and the transducer elements are driven by a plurality of transmission driving circuit. The signal received by the transducer element is distributed to any of a plurality of input terminals of a cross point switch beam former. The received signals of the three transducer elements near the center of the aperture of the ultrasonic probe are added and inputted to one terminal of a beam former. The second, fourth and sixth transducer elements at the end of the aperture are not connected to the beam former. The signals received by the transducer elements are delay-added by the beam former. The delay precision can be improved, and the beam shape can be made sharper, thereby improving the image quality of the ultrasonic image.

    • In general, the invention provides a magnetic head device and linear tape drive that widen the high frequency side of the servo range. In particular, the invention provides a magnetic head device comprising a magnetic head chip with multiple magnetic elements arranged for recording or playback of multiple tracks and a fine positioning structure that uses a bimodal construction that may widen the high frequency side of the servo range by increasing the resonant frequency of the magnetic head chip including the tracking structure and lowering the Q value of the resonance point. In addition, the invention includes a damping structure suitable for the fine positioning structure that improves high speed response by widening the range in which the magnetic head device can be used for a servo. The magnetic head device may use a linear tape drive method.
