摘要： An example dielectric information apparatus is provided with a plurality of electrodes for recording information in a small area of a dielectric substance and an earthed electrode. The electrodes are placed such that the dielectric substance is sandwiched therebetween. The dielectric information apparatus reads out the information recorded in the small area of a dielectric thin film by applying alternating current signals to the first electrodes. The polarization direction of the small area and the direction of an applied electric field decide the dielectric constant of the small area, and the oscillation frequency of an oscillator is determined by a capacitance Cs corresponding to the dielectric constant. An oscillation signal of the oscillator is demodulated at an FM demodulator, and the information is detected from the demodulated signal at a signal detector. When recording, record signals are applied to the first electrodes, and the polarization direction is set to correspond to the record signals.

摘要： A dielectric recording/reproducing head is provided with: a probe; a return electrode for returning a high-frequency component of an electric field applied from the probe; and bias electrodes, which are placed under the return electrode. By applying a voltage stronger than a coercive electric field between the probe and each of the bias electrodes, polarization domains are formed which have polarization directions parallel to a surface of a dielectric recording medium. The polarization directions are determined by selecting the bias electrode to which the voltage is applied, and four types of data are recorded on a predetermined site of the dielectric recording medium, which allows multivalued recording. Moreover, the polarization directions of the polarization domains are detected by an electric field which is formed by applying a voltage between the bias electrodes and which is parallel to the surface of the dielectric recording medium, causing data to be read out.

摘要： The dielectric recording medium is provided with a dielectric material, a conductive thin film, and a substrate. The conductive thin film and the substrate are bonded by a resin adhesive. The dielectric material is constructed of a ferroelectric single crystal having a uniform thickness, and its one surface is used for a recording and/or reproducing surface, on the order of mm on a side and about 5000 Å thick. The conductive thin film, about 1000 to 2000 Å thick, is placed on a surrounding portion and a back surface of the recording and/or reproducing surface of the dielectric material. The substrate is intended to preserve the thin dielectric material and maintain the planarity, and concave portions are formed on the adhesive surface. The concave portions absorb excessive resin adhesive when the dielectric material is bonded onto the substrate, which makes the adhesive surface uniform and flat.

摘要： A piezoelectric thin-film acoustic wave device formed of a piezoelectric thin film of AlN on the +C plane and having the polarization strength of not lower than 0.63×10−20 F/V and an information processing unit using the same are disclosed. This is the result of the inventors having studied the factors other than the C-axis orientation affecting the electromechanical coupling factor and developing a method of improving the electromechanical coupling factor in view of the occasional fact that the electromechanical coupling factor cannot be improved by improving the C-axis orientation and the electromechanical coupling factor required for the piezoelectric thin-film acoustic wave device is not obtained. In such a case, the receiving sensitivity of the receiving system may be deteriorated and the transmission strength of the transmission system is required to be increased undesirably having an adverse effect on the power saving efforts.
